re-appear in almost 200 runs.
So I've now pushed this to emacs-28.

I can't reproduce the error above anymore, with or without the change in

I've tried this in emacs-28, which seems to work, with a caveat

Is this somehow an Emacs-specific problem, or is this a general
problem with libgccjit on those versions of macOS? If the latter, I
think this should be taken up with the libgccjit developers first, and
we should then do as they say, if that makes sense.

If what the libgccjit developers say doesn't fit our needs, or if this
is an Emacs-specific problem, thgen yes, using -Wl,-w is probably the
way to go.

It's okay to make that change on the emacs-28 branch, if someone can
verify that it works on that branch.

I think -w is such an old option that it'd be unthinkable for it not
to be supported.

That is, it builds a shared object (-dynamic).

-bundle_loader is used without -bundle. A "bundle" in Mach-O, which is

I odn't know how to remove the -dynamic from (1).
As an aside, -bundler_loader actually requires an argument <executable>,
which would be Emacs in our case. What that means for Emacs' build
process is unclear to me, but it doesn't feel good.
So, I declare this a complete failure.
Anyone with an idea what else to try? Otherwise my proposal is to
either add something to etc/PROBLEMS describing how to add "-Wl,-w", or
add that option by default on Darwin.
I didn't check if emacs-28 has the same problem, but I don't see why it
wouldn't.
If we add -Wl by default, an open question is if -w is supported on all
all versions of MacOS that Emacs supports, which I can't find a definite
answer to.

This is never the case. Functions in .eln files either call functions in
Emacs core or either call functions in the same .eln file.

Thanks, that works!
(let ((native-comp-driver-options '("-Wl,-w")))
(native-compile "/Users/gerd/emacs/crash.el"))
"/Users/gerd/.emacs.d/eln-cache/29_0_50-72ec8db5/crash-e892b236-cea0f727.el=
n"
Now I guess the question is how to proceed with this... Or maybe wait
for libgccjit to do something?

He writes On the other hand, -undefined dynamic_lookup is already deprecated on all darwin platforms except for macOS, Aha, that's interesting. so it's good time to get rid of the option. ld64 also provides -bundle_loader <executable> option, which allows to resolve symbols defined in the executable symtab while linking. It behaves almost the same with -undefined dynamic_lookup, but it makes the following changes: Require that unresolved symbols among input objects must be defined in the executable. I'm not sure this is true for elns. What if a function in a.eln calls a function F in b.eln? In that case, F wouldn't be defined in the executable. Lazy symbol binding will lookup only the symtab of the bundle loader executable. (-undefined dynamic_lookup lookups all symtab as flat namespace) Not sure what he's saying...

Yeah, that's my problem, too :-)
The ld man page says
Options when creating a bundle
-bundle_loader executable
This specifies the executable that will be loading the bundle
output file being linked. Undefined symbols from the
bundle are
checked against the specified executable like it was one
of the
dynamic libraries the bundle was linked with.
That doesn't look like the right thing.
