Some texlive- packages fail to build non-deterministically.  This one is
on powerpc64le-linux from current master (commit
d904abe0768293b2322dbf355b6e41d94e769d78), but ISTR we saw the same kind
of problem on other architectures before:

Notice the =E2=80=9Crealloc=E2=80=9D message (from glibc) suggesting heap c=

Often, simply retrying yields a successful build.

I just tried building core-updates after the upgrade to TeX Live 2020
(core-updates commit f72a125) and texlive-amscls failed with a slightly
different error coming from glibc, but still indicative of heap corruption:

Hello,

I was able to do a build of texlive-amscls with `export MALLOC_CHECK_=3D2`,=
=20
and a core dump was generated. I managed to get a guix environment with=20
debuginfo for texlive-bin, but for some reason it still doesn=E2=80=99t hav=
e=20
debug info for glibc available. FYI, this was the command line I used:

$ guix environment texlive-amscls --with-debug-info=3Dtexlive-bin \
	--ad-hoc valgrind gdb glibc:debug

Valgrind isn=E2=80=99t working because of the lack of glibc debug info, but=
 I was=20
able to get the backtrace below from the core file, using GDB. I am yet to
analyse it and see if it provides any clue:

Core was generated by `luatex amsclass.ins'.
Program terminated with signal SIGABRT, Aborted.

While investigating luatex crashes in the TeX Live 2020 package of

valgrind: m_mallocfree.c:305 (get_bszB_as_is): Assertion 'bszB_lo =3D=3D bs=
zB_hi' failed.
valgrind: Heap block lo/hi size mismatch: lo =3D 1232, hi =3D 68.
This is probably caused by your program erroneously writing past the
end of a heap block and corrupting heap metadata.  If you fix any
invalid writes reported by Memcheck, this assertion failure will
probably go away.  Please try that before reporting this as a bug.

Does that ring a bell?  Is there a chance this problem was fixed in the
meantime?

Thanks in advance,
Ludovic.

I have bad news and good news. :-)

Unfortunately, TeX Live 2021 still has this bug. I tested version 20210325=
=20
(which is the latest on the historic TeX Live FTP site), with subversion=20
tag texlive-2021.3 (which is the latest tag in the TeX Live repo).

The good news is that I found a simple workaround: use pdftex instead of=20
luatex to build the affected packages. I am currently building all packages=
=20
matching =E2=80=98^texlive=E2=80=99 a few times to find the ones needing th=
is workaround.
So far, I found these:

=E2=80=A2 texlive-amsfonts
=E2=80=A2 texlive-amscls
=E2=80=A2 texlive-babel
=E2=80=A2 texlive-babel-swedish
=E2=80=A2 texlive-latex-amsmath
=E2=80=A2 texlive-generic-babel-english
=E2=80=A2 texlive-latex-cyrillic
=E2=80=A2 texlive-latex-graphics
=E2=80=A2 texlive-latex-tools

I will submit a patch to the guix-patches mailing list (with this bug in=20
Cc:) as soon as the process finishes.

FWIW I managed to get a Valgrind report for TeX Live on core-updates,
using =E2=80=98--extra-debuginfo-path=E2=80=99 to help it a bit:

  https://issues.guix.gnu.org/48064#6

Not that it helps a whole lot yet!

Unfortunately I=E2=80=99m still having problems with glibc debug info and t=
hus
Valgrind doesn=E2=80=99t work for me.

When I use this command:

$ guix environment texlive-amscls --pure	\
	--with-debug-info=3Dtexlive-bin	\
	--ad-hoc valgrind glibc:debug gdb=20

I get luatex linked with this glibc:

$ /bin/which luatex
/gnu/store/s44lh4hqbklplqm3cpaih3rxsv8i1dx1-profile/bin/luatex
$ ldd /gnu/store/s44lh4hqbklplqm3cpaih3rxsv8i1dx1-profile/bin/luatex | grep=
 libc.so
        libc.so.6 =3D> /gnu/store/rhlm1nixi98x09xbyjc4i38gl9xs01f2-glibc-2.=
33/lib/libc.so.6 (0x00007fec0ac3d000)

But for some reason I get debug info for a different glibc:

$ ls -1 /gnu/store/s44lh4hqbklplqm3cpaih3rxsv8i1dx1-profile/lib/debug/gnu/s=
tore/

Yes, you need debug info for (@@ (gnu packages commencement)
glibc-final), which is not what you get when you type =E2=80=9Cglibc:debug=
=E2=80=9D.

Thanks! I was able to run Valgrind on LuaTeX 1.13.0, which is the latest=20
one in TeX Live 2021.

The invalid reads and writes don=E2=80=99t happen on every run. I had to re=
=2Drun the=20
command 3 or 4 times until I got the result below (which matches our=20
experience with the build failures in Guix packages)

=2D-=20
Thanks,
Thiago

valgrind: m_mallocfree.c:303 (get_bszB_as_is): Assertion 'bszB_lo =3D=3D bs=
zB_hi' failed.
valgrind: Heap block lo/hi size mismatch: lo =3D 1248, hi =3D 102.
This is probably caused by your program erroneously writing past the
end of a heap block and corrupting heap metadata.  If you fix any
invalid writes reported by Memcheck, this assertion failure will
probably go away.  Please try that before reporting this as a bug.

Note: see also the FAQ in the source distribution.
It contains workarounds to several common problems.
In particular, if Valgrind aborted or crashed after
identifying problems in your program, there's a good chance
that fixing those problems will prevent Valgrind aborting or
crashing, especially if it happened in m_mallocfree.c.

If that doesn't help, please report this bug to: www.valgrind.org

In the bug report, send all the above text, the valgrind
version, and what OS and version you are using.  Thanks.

It did, thanks for the tip! For the record, this is the command line that=20
worked for me:

$ guix environment texlive-amscls --pure	\
	--with-debug-info=3Dtexlive-bin	\
	--ad-hoc			\
	-e '(list (@@ (gnu packages commencement) glibc-final) =E2=80=9Cdebug=E2=
=80=9D)=E2=80=99  \
	valgrind gdb

Then I pointed valgrind at the /lib/debug directory in the environment=E2=
=80=99s=20
profile, as seen in my previous message.

=2D-=20
Thanks,
Thiago

LuaTeX has a bug where sometimes it corrupts the heap and aborts. This
causes the build of texlive packages to fail at random. The problem is
being tracked at https://issues.guix.gnu.org/48064.

While a fix isn't found, switch the default TeX format (and consequently
also the engine) to pdftex to avoid the issue.

* guix/build-system/texlive.scm (texlive-build): Change default value of
the ‘tex-format’ key parameter to “pdftex”.

Hello,

Originally I had a bigger patch which changed packages individually to
build with pdfTeX, because I thought the bug in LuaTeX was triggered only
by specific packages. As I changed more and more packages though, I
realized that any package can trigger the problem and the heap corruption
happens at random.

Therefore, to work around the LuaTeX bug we need to build all packages with
pdfTeX. I tested the patch with this script:

--8<---------------cut here---------------start------------->8---
#!/bin/bash

set -e

LOG_FILE="$1"
ROUNDS=$2

function verify_package() {
    local package="$1"
    local log_file="$2"

    if ! guix build "$package"; then
        echo "failure while building $package" >> "$log_file"
        return
    fi

    echo "success while building $package" >> "$log_file"

    if ! guix build --check --rounds=$ROUNDS "$package"; then
        echo "failure while checking $package" >> "$log_file"
        return
    fi

    echo "success while checking $package" >> "$log_file"

    return
}

guix describe >> "$LOG_FILE"
echo rounds = "$ROUNDS" >> "$LOG_FILE"
echo >> "$LOG_FILE"

for package in $(guix package --list-available='^texlive' | cut -f1)
do
    verify_package $package "$LOG_FILE"
done
--8<---------------cut here---------------end--------------->8---

and called it with `./verify-texlive-packages.sh verify-packages.log 5`.

I see some packages fail during `guix build --check` because they don't
build deterministically for some reason (which is a separate problem), but
I don't see any package failing to build anymore.

We haven=E2=80=99t heard from dev-luatex yet.  I think we should go with th=
is
workaround for now (those build failures are frequently preventing
evaluations at <https://ci.guix.gnu.org/jobset/core-updates> from
completing, which is a real bummer).  Does using =E2=80=98pdftex=E2=80=99 r=
ather than
=E2=80=98luatex=E2=80=99 have an impact on the output of these packages?

Thanks!

On IRC there were concerns about Unicode support, which LuaTeX provides
but pdftex doesn=E2=80=99t (IIUC), but it would seem that the worst that can
happen is that documentation of the packages themselves would be
mangled, which is okay.

Anyway, it=E2=80=99d be ideal to get feedback from the LuaTeX folks!

Thank you!

I chose pdfTeX for the workaround because it=E2=80=99s the direct =E2=80=9C=
predecessor=E2=80=9D to=20
LuaTeX, so I thought it would behave most similarly to it. But it=E2=80=99s=
 just an=20
uneducated guess.

Searching around a bit=C2=B9=C2=B2=C2=B3, XeTeX also has native Unicode sup=
port, so we=20
could also switch to it. Either as the default, or for specific packages=20
that need it.

NB: I last used TeX more than 15 years ago, and even then just lightly and=
=20
sporadically. Don=E2=80=99t trust my judgement on TeX-related issues. :-)

Agreed!
