--- Comment #2 from Jason Merrill <jason at gcc dot gnu.org> --- Author: jason Date: Wed Mar 6 20:28:47 2019 New Revision: 269442 URL: https://gcc.gnu.org/viewcvs?rev=269442&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.
