--- Comment #4 from Jason Merrill <jason at gcc dot gnu.org> --- Author: jason Date: Fri Mar 8 21:39:58 2019 New Revision: 269509 URL: https://gcc.gnu.org/viewcvs?rev=269509&root=gcc&view=rev Log: PR c++/89381 - implicit copy and using-declaration. Here the used base<int>::operator= gets into the list of foo's bindings for operator=, but it shouldn't make the copy ctor deleted. * class.c (classtype_has_move_assign_or_move_ctor_p): Don't consider op= brought in by a using-declaration.
