Yes, the compiled program when executed will replay the same compilation
attempted by Emacs and therefore if is a libgccjit fault it should
crash.
Does the reproducer crash when executed on your system?

Thanks, I'm going to have a look if I can reproduce here.

The reproducer file is a file that is meant to recreate the same
libgccjit IR and attempt a compilation with that. In practice it calls
the same functions we call at the interface with libgccjit describing
the code we want to compile and attempt to perform a compilation.

I'm not sure why these characters are there but I don't think they are
relevant to the crash.
Thanks!
