It is not visible to middle-end though. If you check gimple dump, there
are calls
jan@padlo:/tmp> grep _M_create a-tt.C.*gimple
_4 = std::__cxx11::basic_string<char>::_M_create (this, &__dnew, 0);
_4 = std::__cxx11::basic_string<char>::_M_create (this, &__dnew, 0);
but no function definition....
So somehow we decide it is not useful to lower it to gimple. Is it
keyed to libstdc++.so?
