Possibly relevant? But seems to be about one specific test and windows.

Steps to Reproduce and Observed Behavior

My native host environment is x86-64 linux.

Tried building zig from source and running its tests for the first time. It seems like test-incremental tests are flaky for me; sometimes only a few fail, sometimes many more. I'm not sure whether there's a pattern.

I built zig follwing the readme, ie.

• build llvm in release mode according to readme instructions
• cmake -B build -GNinja -DCMAKE_PREFIX_PATH=$HOME/local/llvm21-assert -DCMAKE_BUILD_TYPE=Release -DZIG_NO_LIB=ON
• ninja install
• stage3/bin/zig build -p stage4 -Denable-llvm -Dno-lib
• stage4/bin/zig build test -Dskip-release -Dskip-non-native

I've tried running the incremental tests manually with stage4/bin/zig build --summary all -Dskip-release=true -Dskip-non-native=true -Denable-llvm=true test-incremental. Also tried with -Duse-llvm=true, seems to make no difference.

Removing .zig-cache in the root zig directory and rebuilding/rerunning the tests causing a different set of tests to fail.

example output of failing tests:

zig/build$ stage4/bin/zig build --summary all -Dskip-release=true -Dskip-non-native=true -Denable-llvm=true test-incremental

Running one of the failed incr-check commands manually with --preserve-tmp and then running the root executable manually I get a segfault.

Running it gdb doesn't give me much

Expected Behavior

I expected the tests to succeed or not be run by default if they're considered flaky.
