The build is configured with --enable-llvm-assertions, but then we pass "-DLLVM_ENABLE_ASSERTIONS=OFF" to cmake...

We end up with rustc thinking LLVM was build with assertions even though it wasn't.

nikic · 2025-06-14T09:43:50Z

I'm gonna guess it's related to this extra config file

rust/src/ci/docker/host-x86_64/x86_64-gnu-nopt/Dockerfile

Line 32 in 64033a4

    
           ENV SCRIPT python3 ../x.py test --stage 1 --config /config/nopt-std-config.toml library/std \

and the stage redesign in some way... (cc @Kobzol @onur-ozkan)

jieyouxu · 2025-06-14T13:35:38Z

Looking into that.
