We updated our llvm-platform dependency from version 8.0.0-1.5.1 to 9.0.0-1.5.2. After updating we are unable to use the clang API, because it hangs on clang.clang_createIndex(). We can easily reproduce it by running the provided ClangASTVisitorExample with llvm-platform 9.0.0-1.5.2 dependency on windows x64.
