[cfe-dev] libc++ warning

[Seth Cantrell]

Does anyone else see a bunch of warnings like the following when building libc++? I started seeing them a quite a while ago.

> ld: warning: direct access in __ZSt17__throw_bad_allocv to global weak symbol __ZTISt9bad_alloc means the weak symbol cannot be overridden at runtime. This was likely caused by different translation units being compiled with different visibility settings.
