[cfe-dev] Multiple-defined __destructor_1, __destructor_8 when building with recent clang-cl

[Stephan Bergmann via cfe-dev]

After a recent pull of LLVM/Clang trunk, my clang-cl build of 
LibreOffice on Windows started to fail to link some DLL because of 
__destructor_1 and __destructor_8 symbols defined in multiple objects.

I haven't been able yet to strip that down, and looking at the objects' 
assembler output it isn't clear to me what those symbols are emitted for.

Do those symbols maybe ring a bell for anybody?  Is that some recent 
addition?
