--- Comment #6 from Jason Merrill <jason at gcc dot gnu.org> --- Author: jason Date: Thu Sep 20 17:09:19 2018 New Revision: 264442 URL: https://gcc.gnu.org/viewcvs?rev=264442&root=gcc&view=rev Log: PR c++/87075 - ICE with constexpr array initialization. My patch of 2016-08-26 to avoid calling a trivial default constructor introduced TARGET_EXPRs initialized with void_node to express trivial initialization. But when this shows up in a VEC_INIT_EXPR, we weren't prepared to handle it. Fixed by handling it explicitly in cxx_eval_vec_init_1. * constexpr.c (cxx_eval_vec_init_1): Handle trivial initialization. Added: trunk/gcc/testsuite/g++.dg/cpp1y/constexpr-array6.C Modified: trunk/gcc/cp/ChangeLog trunk/gcc/cp/constexpr.c
