No, it's entirely expected. The std::logic_error and std::runtime_error classes
always use a reference counted string type even when std::string is a typedef
for the non-reference counted std::__cxx11::basic_string<char>.
This is one of many reasons that building libstdc++ with LTO is not supported,
and will probably break.
I have some ideas for using a separate ref-counted string type in the
exceptions, so that it's neither the COW std::basic_string nor the __cow_string
kluge, but it's not a priority.
