You mean the other way around? In the test case you're checking for basic_string.

I suspect the difference comes from tuning for lldb on Darwin (do we tune the test suite for lldb on other platforms? probably not?). When tuning for LLDB we generate slightly different debug-info so LLDB knows to show std::string in typenames instead of the basic_string
