--- Comment #3 from CVS Commits <cvs-commit at gcc dot gnu.org> --- The trunk branch has been updated by Andrew Pinski <pins...@gcc.gnu.org>: https://gcc.gnu.org/g:ceba66ee230bb96b0889fc8ec7333c7ffae96d6e commit r13-4144-gceba66ee230bb96b0889fc8ec7333c7ffae96d6e Author: Andrew Pinski <apin...@marvell.com> Date: Thu Nov 17 22:03:08 2022 +0000 Fix PR middle-end/107705: ICE after reclaration error The problem here is after we created a call expression in the C front-end, we replace the decl type with an error mark node. We then end up calling aggregate_value_p with the call expression with the decl with the error mark as the type and we ICE. The fix is to check the function type after we process the call expression inside aggregate_value_p to get it. OK? Bootstrapped and tested on x86_64-linux-gnu with no regressions. Thanks, Andrew Pinski gcc/ChangeLog: PR middle-end/107705 * function.cc (aggregate_value_p): Return 0 if the function type was an error operand. gcc/testsuite/ChangeLog: * gcc.dg/redecl-22.c: New test.
