    it seems regression [LLVM 21.1.0-rc1](https://github.com/llvm/llvm-project/releases/tag/llvmorg-21.1.0-rc1) from last release [LLVM 20.1.8](https://github.com/llvm/llvm-project/releases/tag/llvmorg-20.1.8)
i got infinet loop while try compile with clang-cl.exe for win64
i did not check clang-cl.exe for win32 and clang.exe
right now try get clang-cl.pdb @zmodem to show some backtrace
