Those tests fail when linking against a new dylib but running against macosx10.7. I believe this is caused by a duplicate definition of the RTTI for exception classes in libc++.dylib and libc++abi.dylib, but this matter still needs some investigation. This issue was not caught previously because all the tests always linked against the same dylib used for running (because LIT made it impossible to do otherwise before r349171). rdar://problem/46809586 llvm-svn: 354940
