 You're seeing the mangled names.  In theory, if you ran those names through
 the demangler (c++filt), you'd see the "human" names.
 
 In practice, as of today, those aren't what c++filt is looking for, so
 the demangler doesn't demangle them.  The names themselves are correct,
 but they're missing the 'local prefix':
 
     % echo St9exception | ~/build/install-2001-05-25-3branch/bin/c++filt
     St9exception
     % echo _ZSt9exception | ~/build/install-2001-05-25-3branch/bin/c++filt
     std::exception
