It was actually `git bisect` which pointed to me to this patch, it could be a side-effect of it.

Will surely do, I don't have a simple repro yet.

I'm also seeing a 3rd issue, different from the ones reported above, but it might all be the same thing:

  clang-cl: /mnt/llvm-project/clang/lib/CodeGen/CGCleanup.cpp:1322: void EmitSehScope(clang::CodeGen::CodeGenFunction &, llvm::FunctionCallee &): Assertion `BB && InvokeDest' failed.
  PLEASE submit a bug report to https://bugs.llvm.org/ and include the crash backtrace, preprocessed source, and associated run script.
