--- Comment #25 from Jonathan Wakely <redi at gcc dot gnu.org> --- Yes, and it 1) refers to the key function and 2) is done by the linker not the compiler. Which is what I've been suggesting. If binutils wants to do this and wants to provide a URL, we'll need a more permanent home for the info at https://gcc.gnu.org/wiki/VerboseDiagnostics#undefined_reference_to_vtable_for_X -- You are receiving this mail because: You reported the bug.
