--- Comment #5 from Sam James <sjames at gcc dot gnu.org> --- Created attachment 60204 --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=60204&action=edit macroexp-2c3e1495-c0b1cf80_libgccjit_repro.c.xz Attached macroexp-2c3e1495-c0b1cf80_libgccjit_repro.c after patching Emacs to unconditionally dump it (it already had a debug path for it). The GC checking bool didn't change anything there. I can't reproduce it manually using this C file yet tho.
