--- Comment #6 from GCC Commits <cvs-commit at gcc dot gnu.org> --- The master branch has been updated by Patrick Palka <[email protected]>: https://gcc.gnu.org/g:e873aac49eb2b58ae18e05f4150826278bdbb3cb commit r17-2839-ge873aac49eb2b58ae18e05f4150826278bdbb3cb Author: Patrick Palka <[email protected]> Date: Thu Jul 30 21:18:38 2026 -0400 c++: resolvedness of resolve_nondeduced_context result [PR126406] In r16-5967-gbae0ed69e1862a we removed the mark_used call from resolve_nondeduced_context under the rationale that it should be the caller's responsiblity to mark_used. Removing the call however now means that resolve_nondeduced_context could return a specialization whose type is not yet fully resolved (i.e. has an uninstantiated noexcept or undeduced return type), and callers that immediately inspect TREE_TYPE of the result (such as standard_conversion and build_conditional_expr) now misbehave. In light of such callers, this patch reverts r16-5967; it's not necessary to fix PR119343 because after r16-6276 convert_to_void now properly propagates an error_mark_node result from resolve_nondeduced_context.
