--- Comment #5 from CVS Commits <cvs-commit at gcc dot gnu.org> --- The trunk branch has been updated by Marek Polacek <mpola...@gcc.gnu.org>: https://gcc.gnu.org/g:2cb0dc866e8f95151df5d759157708108e850dd9 commit r14-2677-g2cb0dc866e8f95151df5d759157708108e850dd9 Author: Marek Polacek <pola...@redhat.com> Date: Wed Jul 19 08:47:29 2023 -0400 c++: fix ICE with designated initializer [PR110114] r13-1227 added an assert checking that the index in a CONSTRUCTOR is a FIELD_DECL. That's a reasonable assumption but in this case we never called reshape_init due to the type being incomplete, and so the index remained an identifier node: get_class_binding never got around to looking up the FIELD_DECL. We can avoid the crash by returning early in implicit_conversion_1; we'd return NULL anyway due to: if (i < CONSTRUCTOR_NELTS (ctor)) return NULL; in build_aggr_conv.
