https://gcc.gnu.org/bugzilla/show_bug.cgi?id=95133 --- Comment #5 from CVS Commits --- The master branch has been updated by Richard Biener : https://gcc.gnu.org/g:aaf1ee48316f9b414b11c17e298198925d816595 commit r11-414-gaaf1ee48316f9b414b11c17e298198925d816595 Author: Richard Biener Date: Fri May 15 09:38:54 2020 +0200 tree-optimization/95133 - avoid abnormal edges in path splitting When path splitting tries to detect a CFG diamond make sure it is composed of normal (non-EH, not abnormal) edges. Otherwise CFG manipulation later may fail. 2020-05-15 Richard Biener PR tree-optimization/95133 * gimple-ssa-split-paths.c (find_block_to_duplicate_for_splitting_paths): Check for normal edges. * gcc.dg/pr95133.c: New testcase.
