commit r12-10467-g419b5e17eace9b6b985b9853db0dc1a5478375b6 Author: Jason Merrill <ja...@redhat.com> Date: Thu Jan 25 12:02:07 2024 -0500 c++: array of PMF [PR113598] Here AGGREGATE_TYPE_P includes pointers to member functions, which is not what we want. Instead we should use class||array, as elsewhere in the function. PR c++/113598 gcc/cp/ChangeLog: * init.cc (build_vec_init): Don't use {} for PMF. gcc/testsuite/ChangeLog: * g++.dg/cpp0x/initlist-pmf2.C: New test.
