--- Comment #3 from CVS Commits <cvs-commit at gcc dot gnu.org> --- The master branch has been updated by Richard Biener <rgue...@gcc.gnu.org>: https://gcc.gnu.org/g:ad08894ea02b6308c4ed4e8cd8e6a564c2f581e8 commit r13-2639-gad08894ea02b6308c4ed4e8cd8e6a564c2f581e8 Author: Richard Biener <rguent...@suse.de> Date: Tue Sep 13 08:46:51 2022 +0200 tree-optimization/106913 - ICE with -da and -Wuninitialized The following avoids setting and not clearing an auto_bb_flag on EXIT_BLOCK which we don't verify for such stale flags but dump_bb_info still asserts on them. PR tree-optimization/106913 * tree-ssa-uninit.cc (warn_uninitialized_vars): Do not set ft_reachable on EXIT_BLOCK.
