--- Comment #9 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:b03ad138a61f64d8a77876d6864aad5103fff498 commit r13-4181-gb03ad138a61f64d8a77876d6864aad5103fff498 Author: Andrew Pinski <apin...@marvell.com> Date: Sat Nov 19 12:48:27 2022 -0800 Fix PR 106560: Another ICE after conflicting types of redeclaration This another one of these ICE after error issues with the gimplifier and a fallout from r12-3278-g823685221de986af. The problem here is gimplify_modify_expr does not check if either from or to was an error operand. This adds the check and fixes the ICE. OK? Bootstrapped and tested on x86_64-linux-gnu with no regressions. gcc/ChangeLog: * gimplify.cc (gimplify_modify_expr): If either *from_p or *to_p were error_operand return early. gcc/testsuite/ChangeLog: * gcc.dg/redecl-23.c: New test. * gcc.dg/redecl-24.c: New test. * gcc.dg/redecl-25.c: New test.
