Zig 0.14 bootstrap fails on Void Linux
Description
Recently, building zig on Void Linux ends up in a segfault during the stage3 step.
The issue started happening roughly after we updated system toolchain to gcc 14.2.1, and curiously enough, doesn't reproduce with musl libc.
Info
Zig version: 0.14.0, 0.14.1
Zig package PR: https://github.com/void-linux/void-packages/pull/54650

I mean this really looks like either a bug in LLVM or a miscompilation by GCC to me.
FWIW I got the same result when
a) using LLVM instead of GCC as compiler b) updating LLVM version used by zig from 19.1.4 to 19.1.7
(This may well be an upstream or downstream issue, but labeling and milestone-ing for now so it doesn't get lost.)
getting similar issues here on Debian trying to build 0.14.1 from source.

FWIW I got the same result when
a) using LLVM instead of GCC as compiler b) updating LLVM version used by zig from 19.1.4 to 19.1.7
Hello, late to the party, I have tried other gcc versions in openSUSE, and the one that works is gcc 7. i am quite not sure if this is relevant. Tested image is leap 15.6 and opensuse:factory (since both have gcc 7).
Maybe I'll open a new issue since this is a different distribution? I am hesitating since the original C compiler I set was clang 19.x. I tried testing other C compilers like gcc versions 7 to 13. I also have the same errors like this issue when using clang except it only happens in openSUSE:Factory image. It builds successfully on x86_64 images of leap 15.6 and leap 16.0. I will share logs later since I didn't save them.
FWIW, the bleeding edge build got past stage3 without issue (with Clang 20).
With more debug info:
#0 (anonymous namespace)::ConstantFoldScalarCall1 (Name=..., IntrinsicID=165, Ty=0x7fffbcb78818, Operands=..., TLI=0x0, Call=0x7fffbd415160) at /usr/src/debug/llvm-19.1.7.src/lib/Analysis/ConstantFolding.cpp:2127
We're at https://github.com/llvm/llvm-project/blob/llvmorg-19.1.7/llvm/lib/Analysis/ConstantFolding.cpp#L2127. So the problem is a null pointer access (TLI=0x0). This should be fixed by https://github.com/llvm/llvm-project/commit/83a5c7cb62e404a713a35445b755cf0109650279.
