This is a meta bug to cover all known Clang vs Microsoft C++ ABI incompatibility / unsupportness.
Bug 9213 might be relevant to this. It's an issue in llvm, though.
Timur, I cleaned up this bug my moving all the non-ABI related to PR 13707. If you think I moved something that belongs in this one (or missed some) let me know (or fix it).
Sure, thanks!
