--- Comment #8 from Jason Merrill <jason at gcc dot gnu.org> --- Author: jason Date: Fri Jan 10 18:47:02 2020 New Revision: 280127 URL: https://gcc.gnu.org/viewcvs?rev=280127&root=gcc&view=rev Log: PR c++/93143 - incorrect tree sharing with constexpr. We don't unshare CONSTRUCTORs as often during constexpr evaluation, so we need to unshare them here. * constexpr.c (cxx_eval_outermost_constant_expr): Don't assume CONSTRUCTORs are already unshared. Added: trunk/gcc/testsuite/g++.dg/cpp0x/constexpr-array22.C Modified: trunk/gcc/cp/ChangeLog trunk/gcc/cp/constexpr.c
