--- Comment #3 from CVS Commits <cvs-commit at gcc dot gnu.org> --- The master branch has been updated by Jason Merrill <ja...@gcc.gnu.org>: https://gcc.gnu.org/g:0712ea6313bc44f9ae8feb235c1b02c92cdd0527 commit r10-6437-g0712ea6313bc44f9ae8feb235c1b02c92cdd0527 Author: Jason Merrill <ja...@redhat.com> Date: Tue Feb 4 15:54:17 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. PR c++/90951 * constexpr.c (cxx_eval_array_reference): {}-initialize missing elements instead of value-initializing them.
