Hi, guys! Our users (MSYS2) report lot of crashes in different applications. We found that that crash are happen after upgrading winpthreads and caused one or both of two commits: Rewrite the pthread spin lock implementation - https://github.com/msys2/mingw-w64/commit/249898d9ae310959116efa333e4e3e690cf97452 <https://github.com/msys2/mingw-w64/commit/249898d9ae310959116efa333e4e3e690cf97452> Rewrite the mutex implementation for better performance - https://github.com/msys2/mingw-w64/commit/1968e60cd5d59727bb325d5b69c8f0d7a2f1fe1b <https://github.com/msys2/mingw-w64/commit/1968e60cd5d59727bb325d5b69c8f0d7a2f1fe1b>
