--- Comment #1 from Bernd Edlinger <bernd.edlinger at hotmail dot de> --- with -std=gnu++03 we get call _ZNSt7__cxx1112basic_stringIcSt11char_traitsIcESaIcEE5eraseEN9__gnu_cxx17__normal_iteratorIPKcS4_EES9_ aka std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> >::erase(__gnu_cxx::__normal_iterator<char*, std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> > >, __gnu_cxx::__normal_iterator<char*, std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> > >) which is not in -lstdc++ but with -std=gnu++11 we get call _ZNSt7__cxx1112basic_stringIcSt11char_traitsIcESaIcEE5eraseEN9__gnu_cxx17__normal_iteratorIPcS4_EES8_ aka std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> >::erase(__gnu_cxx::__normal_iterator<char const*, std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> > >, __gnu_cxx::__normal_iterator<char const*, std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> > >) which is found in -lstdc++ so the difference is in the constness of the iterator parameters.
