Has this bug been fixed in the post 2.37.0 work so far?

https://github.com/conan-io/conan-center-index/issues/25353

Although it was reported to that Conan repository, I suspect it has not been reported upstream.

I've also run into it with Homebrew Clang 18 and 19.

Thanks,

This wasn't brought to my attention earlier. Thanks for letting me know.

I will have a look at it, but as I do not have a Mac with x86 env set up I don't know if I'll be able to fix it.

The same code works with clang on Linux. So it appears to be something specific to Mac.

If you could suggest a fix that would be helpful.

Thanks,
Andreas

We are seeing the same thing with the macOS 15 update in vcpkg: https://github.com/microsoft/vcpkg/pull/43509

It looks like they also deprecated some atomics stuff AngelScript uses: https://github.com/microsoft/vcpkg/blob/67289b82d6af3557df612be5ad2efd8801621db5/ports/angelscript/avoid-atomic-deprecation-macos-15.diff

Perhaps Clang on Linux with the right control flow integrity switches flipped could repro? Looks like the bit that emits this was added in 2023: https://github.com/llvm/llvm-project/commit/0b0672773e8b2ed01ad3fce103f4d84becfdd1ed according to https://github.com/llvm/llvm-project/issues/89087
