I believe this is the same bug as 43175.

There is a fix for it, but it's not in 9.0.0 or the branch for a 9.0.1 release.

This bug has been marked as a duplicate of bug llvm/llvm-project#42520

36b91afb-f5cc-49ee-aa5a-982348a9b5aa commented 4 years ago

I changed the component to OpenMP because I get the same issue with std=c++14 and nailed it down to a problem with OpenMP and std::regex used together.

Note that this is a regression from 8.0.1. It works with the old clang-cl.

I'm pretty sure that this is the same issue as described by Celestin because her/his example also contains OpenMP and prints a similar error message related to std::regex.

36b91afb-f5cc-49ee-aa5a-982348a9b5aa commented 4 years ago

Error message when compiled with OpenMP (std::regex usage) Trigger the crash via: clang-cl regex.cpp -Xclang -fopenmp This runs smoothly: clang-cl regex.cpp

Both of them were working with clang-cl 8.0.0 and 8.0.1 on my system.
