Thanks, and I'll try to look in to this further when I have time. For
now I'm changing the debian packages to avoid native compilation on some
architectures (currently mips64el[1] and s390x).
[1] There ./configure fails at the moment with "Error: -march=mips1 is
not compatible with the selected ABI" when testing libgccjit.
That's on eller.debian.org (mipsel host in a mips64el schroot).

The code where this happens is this:
for (int i = 0; i < staticidx; i++)
visitor.visit (staticvec[i], GC_ROOT_STATICPRO, visitor.data);
So one way of knowing which staticpro is being handled here is to see
what is the value of 'i' and look at staticvec[i]. I'm guessing that
'i' is also "optimized out", though, so 2 possible ways forward:
. disassemble visit_static_gc_roots, find in which register or where
on the stack or in memory is 'i; or staticvec[i] stored, and go
from there; or
. add a printf to the above loop to show the value of 'i', and
re-run the build, fingers crossed, hoping that the additional
printf won't make the crash go away.
Once you know which staticpro is being processed here, we'd need to
examine its contents and try to figure out which parts cause the crash
in GC.
Thanks.

Sorry, I thought another Emacs developer would chime in, when I wrote
that.
Let me try to explain what I'm after. Frame#7, the call to
visit_static_gc_roots shows that we are at the very beginning of a GC,
recursively marking everything that we know must survice the GC.
void
visit_static_gc_roots (struct gc_root_visitor visitor)
{
visit_buffer_root (visitor,
&buffer_defaults,
GC_ROOT_BUFFER_LOCAL_DEFAULT);
visit_buffer_root (visitor,
&buffer_local_symbols,
GC_ROOT_BUFFER_LOCAL_NAME);
for (int i =3D 0; i < ARRAYELTS (lispsym); i++)
{
Lisp_Object sptr =3D builtin_lisp_symbol (i);
visitor.visit (&sptr, GC_ROOT_C_SYMBOL, visitor.data);
}
for (int i =3D 0; i < staticidx; i++)
visitor.visit (staticvec[i], GC_ROOT_STATICPRO, visitor.data);
}
First interesting thing would be where in this function we are when the
crash happens. I was assuming it is somewhere in the last for-loop, for
reasons, but that doesn't have to be the case.
If I'm right, we are currently in the process of marking Lisp objects
referenced from C variables that are known to contains Lisp objects.
Such variables are added to staticvec with a call to staticpro. That's
what the staticpro in my last mail menat.
But let's first see where in visit_... we are.

The fact that even -g has an impact here clearly shows that initial conditions are not necessary directly connected with the final symptom we observe. Best Regards Andrea

Mmmh one cheap way to maybe gather more info is to have a run under valgrind. Other than that I typically start debugging with GDB and possibly rr. Like what is (or was) the object the GC is crashing on? Why? What's the last piece of code that touched it? Why? IIUC here we have no debug symbols so this makes it very difficult. BTW the fact that -g has an impact on the crash is very odd Andrea

Perhaps Andrea or Paul could comment. > Throwing -fno-strict-aliasing in the mix is a bit like throwing -O1 into the mix. I'm not surprised it would cause a Heisenbug to vanish; it doesn't mean strict aliasing is the problem. Emacs should work with strict aliasing. At least, that's true in the default build. I suppose it could be possible there's a strict aliasing bug in the native compiler - I'm not that familiar with that code.

Thanks. The backtrace indicates that the crash is in GC. This probably means we have some fundamental problem on that architecture. Andrea, any advice for how to investigate? Does the build of the same code with the same options sans "--with-native-compilation" succeed, or does it also crash with similar symptoms? If the build without native-compilation succeeds, my first question would be how mature and stable is libgccjit on that platform? Perhaps take this up with the GCC's libgccjit developers. > With respect to the Lisp-level backtrace, I imagined you probably meant > an xbacktrace? If so (and assuming I'm guessing right about how I > should do that), I haven't figured out how to arrange sourcing the > src/.gdbinit from the src/Makefile.in command. You can source it manually from the GDB prompt, when the segfault happens, and then invoke xbacktrace manually, can't you? > It looked like it might be because there were no debug symbols, so I > tried adding a CFLAGS=-g3 to the end of the ./configure, but that caused > the crash to disappear entirely. Too bad, it means we have a heisenbug on our hands, which will make it even harder to debug (as if debugging crashes in GC were not hard enough already). What happens if you modify this variable: (defcustom native-comp-debug (if (eq 'windows-nt system-type) 1 0) to have the value 1 or even zero, and then rebuild from scratch? does the build succeed then? > Finally (and this was just a random guess based on previous experiences, > particularly with programs like guile that play (normal, traditional) > tricks with pointers/coercions/etc.) I noticed that emacs doesn't > specify -fno-strict-aliasing, and unless all the C code has been written > with that in mind, I assume that might open a window allowing the > optimizer to introduce undesirable changes.

Starting from scratch with the emacs-28.1 commit I can reproduce the
failure when building via
./configure --prefix=/home/rlb/opt/emacs-tmp --with-native-compilation
It crashes with the same segfault repeatably, i.e. if you run make
again, it crashes again on the previously mentioned "... -l comp -f
batch-byte+native-compile international/titdic-cnv.el" invocation. That
crash output is attached below.
After adjusting the Makefile.in invocation so I could run it with gdb in
exactly the same environment once it's failing on that command, I
captured the backtrace and included it below.
With respect to the Lisp-level backtrace, I imagined you probably meant
an xbacktrace? If so (and assuming I'm guessing right about how I
should do that), I haven't figured out how to arrange sourcing the
src/.gdbinit from the src/Makefile.in command. I'm likely doing
something wrong, but it doesn't seem to want to load the file.
It looked like it might be because there were no debug symbols, so I
tried adding a CFLAGS=-g3 to the end of the ./configure, but that caused
the crash to disappear entirely.
Finally (and this was just a random guess based on previous experiences,
particularly with programs like guile that play (normal, traditional)
tricks with pointers/coercions/etc.) I noticed that emacs doesn't
specify -fno-strict-aliasing, and unless all the C code has been written
with that in mind, I assume that might open a window allowing the
optimizer to introduce undesirable changes. So I added a
CFLAGS=-fno-strict-aliasing to the end of the ./configure command, and
then the build and tests worked fine (twice in a row):
./configure --prefix=/home/rlb/opt/emacs-tmp --with-native-compilation \
CFLAGS=-fno-strict-aliasing
Of course that's not remotely conclusive, but if all of the C code
wasn't written with strict-aliasing in mind, then I wondered if it might
make sense to consider adding -fno-strict-aliasing as a default option.
Also, even if that ends up being desirable, I'm not sure it'll be
sufficient. That is, I suspect I might want to run the full build/check
with -fno-strict-aliasing in a loop for a bit to make sure the clean
build/check is reliable, since I think I may have seen some test crashes
(not the build crash) on one earlier run with that option, but I'm not
sure that was a clean attempt.
The make crash:

Hmm, so I ran "make V=1" from the same tree and saw thw command that
repeatably crashed, which was:
EMACSLOADPATH= '../src/bootstrap-emacs' -batch --no-site-file --no-site-lisp --eval '(setq load-prefer-newer t)' \
-l comp -f batch-byte+native-compile international/titdic-cnv.el
I then ran that manually via
(cd lisp
&& EMACSLOADPATH= '../src/bootstrap-emacs' -batch --no-site-file --no-site-lisp --eval '(setq load-prefer-newer t)' \
-l comp -f batch-byte+native-compile international/titdic-cnv.el)
which ran for a bit and succeeded. After that a make worked fine until
bindings.el where it crashed again, this time with an "Aborted", and
running it manually didn't help.
In any case, I'm going to start over and try to get the backtraces for
the titdic-cnv.el failure.

On zelenka.debian.org https://db.debian.org/machines.cgi?host=zelenka
the build crashes with a segfault with current Debian sid (unstable). I
can produce the crash like this:
git clone --single-branch --branch emacs-28 .../emacs.git
cd emacs
./autogen.sh
./configure --prefix=/home/rlb/opt/emacs-tmp --with-native-compilation
make check
The debian package produced a similar failure earlier:
https://buildd.debian.org/status/fetch.php?pkg=emacs&arch=s390x&ver=1%3A28.1%2B1-3&stamp=1662863442&raw=0
Here's the final bit of the clone build's log, and I'm happy to help
test on the machine if that'd be useful:
