<pre>With libstdc++ 9.1 and
#include <filesystem>
void foo() {
for (auto& dev : std::filesystem::directory_iterator("slaves")) {
}
}
clang calls
_ZNSt12__shared_ptrINSt10filesystem7__cxx114_DirELN9__gnu_cxx12_Lock_policyE2EEC2EOS5_
and gcc calls
_ZNSt12__shared_ptrINSt10filesystem7__cxx114_DirELN9__gnu_cxx12_Lock_policyE2EEC1EOS5_.
This is a problem because libstdc++ has
extern template class
__shared_ptr<filesystem::_Dir>;
but only
_ZNSt12__shared_ptrINSt10filesystem7__cxx114_DirELN9__gnu_cxx12_Lock_policyE2EEC1
is exported in the .so.</pre>
