--- Comment #3 from GCC Commits <cvs-commit at gcc dot gnu.org> --- The releases/gcc-14 branch has been updated by Iain D Sandoe <ia...@gcc.gnu.org>: https://gcc.gnu.org/g:ee0736f665971446f8665a94ef597f683f8128e9 commit r14-11717-gee0736f665971446f8665a94ef597f683f8128e9 Author: Arsen Arsenovic <ar...@aarsen.me> Date: Tue Jul 30 13:42:56 2024 +0200 c++: fix ICE on FUNCTION_DECLs inside coroutines [PR115906] When register_local_var_uses iterates a BIND_EXPRs BIND_EXPR_VARS, it fails to account for the fact that FUNCTION_DECLs might be present, and later passes it to DECL_HAS_VALUE_EXPR_P. This leads to a tree check failure in DECL_HAS_VALUE_EXPR_P: tree check: expected var_decl or parm_decl or result_decl, have function_decl in register_local_var_uses We only care about PARM_DECL and VAR_DECL, so select only those. PR c++/115906 - [coroutines] missing diagnostic and ICE when co_await used as default argument in function declaration gcc/cp/ChangeLog: PR c++/115906 * coroutines.cc (register_local_var_uses): Only process PARM_DECL and VAR_DECLs. gcc/testsuite/ChangeLog: PR c++/115906 * g++.dg/coroutines/coro-function-decl.C: New test.
