I guess https://gitweb.gentoo.org/proj/gcc-patches.git/tree/11.4.0/musl/50_all_calloc_libgccjit.patch is incomplete and we need to pull in more bits from https://gitweb.gentoo.org/proj/gcc-patches.git/tree/12.1.0/musl/50_all_calloc_libgccjit.patch?id=1acb0022d8e6578a26985b0016757581e43af072 (it's fixed upstream now).

Could you try figure out which bits we're missing?

Ok, I'll check it out and report back my findings the next few days.

[Comment 4 ernsteiswuerfel 2023-01-24 20:12:54 UTC]

Current stable gcc-11.3.1 build of now with current stable gcc-12.2.1.

Thanks Sam!
