Segfault in build-exe

Through some trial and error, I was able to recreate the bug and create a fairly minimal reproduction:

 codegen(c): Fix incorrect union access when calling cast function pointers
nmcdaniel commented on issue ziglang/zig#31528 2026年03月19日 19:03:45 +01:00
Comptime known pointer is 0 in indirect call

On debug builds this doesn't seem to present itself as a miscompilation, but rather a compiler crash. The issue is caused by the assumption that any callee nav value is a function (x86) and...

codegen: support for calling @ptrCast and @ptrFromInt function pointers

I noticed #31528 was a crash in the same code segment, so I made some slight corrections to fix that use case as well.

Segfault when running Zig code that calls C++ code that calls Qt6 functions on self-hosted backend

The problem here is that zig's linker is copying the st_other visibility bits of the symbol from the Qt library shared object. Qt's shared objects use STV_PROTECTED, which disallows external...
