--- Comment #9 from CVS Commits <cvs-commit at gcc dot gnu.org> --- The master branch has been updated by Jakub Jelinek <ja...@gcc.gnu.org>: https://gcc.gnu.org/g:6e2743687202c58a6553ae632ebbada3de38ad48 commit r12-8057-g6e2743687202c58a6553ae632ebbada3de38ad48 Author: Jakub Jelinek <ja...@redhat.com> Date: Fri Apr 8 09:16:30 2022 +0200 c: Error on va_arg with function type [PR105149] In the PR Joseph said that the C standard for va_arg talks about pointers to object type and as a function type is not object type, it is invalid. The following patch diagnoses it in the FE, instead of ICEing later on when optimizations are turned on (and with -O0 doing something weird at runtime). 2022-04-08 Jakub Jelinek <ja...@redhat.com> PR c/105149 * c-typeck.cc (c_build_va_arg): Reject function types. * gcc.dg/pr105149.c: New test.
