Hello everyone,
unfortunately getting a CI run with clang-cl without a complete build on the way took way longer than expected. And I assume my recipe is still not using the expected way, as I had to do a few modifications to get out of crt-hell.
However, this is a run that completed at last my proposed test rtlallocateheap_realloc_in_place.cpp for [i686](https://github.com/bernhardu/llvm-project/actions/runs/14384569847/job/40336590746#step:7:13930) and [x86_64](https://github.com/bernhardu/llvm-project/actions/runs/14384569847/job/40336590759#step:7:3183).
