Ok, got following today with GCC 9.2 with "-O2 -fno-inline -flto=20":
ld.bfd: /tmp/tests.oKru4z.ltrans32.ltrans.o: in function
`std::__shared_ptr::operator=(std::__shared_ptr&&)':

Except -O0, which is what I find surprising.

It will require it

I didn't export that because nothing should need it. Nothing in libstdc++
derives from __shared_ptr<_Dir> and nothing in user code is allowed to refer to
that type, because it's an implementation detail.

I assume that problem comes from explicit instantiation:
extern template class __shared_ptr;
which was added in c8fb3443911413cc88f316305fc6b7bf4861ccaa.
It prevent Clang in emitting "C2" version of

There are also some recursive_directory_iterator symbols missing. This fails
even compiled with GCC:
#include
int main()
{
std::filesystem::recursive_directory_iterator d;
d = d;
}
