--- Comment #5 from CVS Commits <cvs-commit at gcc dot gnu.org> --- The releases/gcc-9 branch has been updated by Jason Merrill <ja...@gcc.gnu.org>: https://gcc.gnu.org/g:831d4a690053599d2d0aa9713642b8513fdf8f5b commit r9-8331-g831d4a690053599d2d0aa9713642b8513fdf8f5b Author: Jason Merrill <ja...@redhat.com> Date: Wed Mar 4 17:30:58 2020 -0500 c++: avoid ICE with __builtin_memset (PR90997). warn_for_memset calls fold_for_warn, which calls fold_non_dependent_expr, so also calling instantiate_non_dependent_expr here is undesirable. gcc/cp/ChangeLog 2020-03-04 Jason Merrill <ja...@redhat.com> PR c++/90997 * semantics.c (finish_call_expr): Don't call instantiate_non_dependent_expr before warn_for_memset.
