--- Comment #5 from CVS Commits <cvs-commit at gcc dot gnu.org> --- The releases/gcc-8 branch has been updated by Jason Merrill <ja...@gcc.gnu.org>: https://gcc.gnu.org/g:300d219af336436fbb58043db193f54d2a1b4b49 commit r8-10054-g300d219af336436fbb58043db193f54d2a1b4b49 Author: Jason Merrill <ja...@redhat.com> Date: Mon Feb 24 16:22:45 2020 -0500 c++: Fix constexpr vs. omitted aggregate init. Value-initialization is importantly different from {}-initialization for this testcase, where the former calls the deleted S constructor and the latter initializes S happily. gcc/cp/ChangeLog 2020-02-24 Jason Merrill <ja...@redhat.com> PR c++/90951 * constexpr.c (cxx_eval_array_reference): {}-initialize missing elements instead of value-initializing them.
