--- Comment #2 from CVS Commits <cvs-commit at gcc dot gnu.org> --- The releases/gcc-10 branch has been updated by Marek Polacek <mpola...@gcc.gnu.org>: https://gcc.gnu.org/g:977a173c196dc5ba5ac2e1b890083beb0451cf60 commit r10-8268-g977a173c196dc5ba5ac2e1b890083beb0451cf60 Author: Marek Polacek <pola...@redhat.com> Date: Wed Jun 10 10:49:08 2020 -0400 c++: Fix ICE with delayed parsing of noexcept-specifier [PR95562] Here we ICE because a DEFERRED_PARSE expression leaked to tsubst_copy. We create these expressions for deferred noexcept-specifiers in cp_parser_save_noexcept; they are supposed to be re-parsed in cp_parser_late_noexcept_specifier. In this case we never got around to re-parsing it because the noexcept-specifier was attached to a pointer to a function, not to a function declaration. But we should not have delayed the parsing here in the first place; we already avoid delaying the parsing for alias-decls, typedefs, and friend function declarations. (Clang++ also doesn't delay the parsing for pointers to function.) gcc/cp/ChangeLog: PR c++/95562 * parser.c (cp_parser_direct_declarator): Clear CP_PARSER_FLAGS_DELAY_NOEXCEPT if the declarator kind is not cdk_id. gcc/testsuite/ChangeLog: PR c++/95562 * g++.dg/cpp0x/noexcept60.C: New test.
