Jakub Jelinek <jakub at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |jakub at gcc dot gnu.org, | |jason at gcc dot gnu.org --- Comment #5 from Jakub Jelinek <jakub at gcc dot gnu.org> --- Indeed. The VOID_CST elts of the CONSTRUCTOR come from the 8352 if (is_dummy_object (argarray[0])) 8353 return force_target_expr (DECL_CONTEXT (fn), void_node, 8354 no_cleanup_complain); that patch added, and the constexpr handling code is upset that there is a VOID_CST rather than CONSTRUCTOR inside of the elts.
