Summary: Undefined symbols in libstdc++ when building with
--with-default-libstdcxx-abi=gcc4-compatible
Product: gcc
Version: 9.1.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: libstdc++

Target Milestone: ---
Hello,
When build gcc-9.1.0 with --with-default-libstdc xx-abi=gcc4-compatible
resulting libstdc++.so.6.0.26 contains following undefined symbols:
U std::__cxx11::basic_string<char, std::char_traits<char>,
std::allocator<char> >::operator std::basic_string_view<char,
std::char_traits<char> >() const
U std::__cxx11::basic_string<char, std::char_traits<char>,
std::allocator<char> >::__sv_wrapper::__sv_wrapper(std::basic_string_view<char,
std::char_traits<char> >)
U std::__cxx11::basic_string<char, std::char_traits<char>,
std::allocator<char> >::_S_to_string_view(std::basic_string_view<char,
std::char_traits<char> >)
U std::__cxx11::basic_string<char, std::char_traits<char>,
std::allocator<char> >::data()
U std::__cxx11::basic_string<char, std::char_traits<char>,
std::allocator<char> >::basic_string(std::__cxx11::basic_string<char,
std::char_traits<char>, std::allocator<char> >::__sv_wrapper,
std::allocator<char> const&)
U std::__cxx11::basic_string<wchar_t,
std::char_traits<wchar_t>, std::allocator<wchar_t> >::data()
As result even minimal 'int main() { return 0; }' C++ program can't be linked.
