--- Comment #4 from GCC Commits <cvs-commit at gcc dot gnu.org> --- The master branch has been updated by Richard Biener <[email protected]>: https://gcc.gnu.org/g:210b4eca880c88e7f7ec970b68a93a2a28bad1be commit r17-2220-g210b4eca880c88e7f7ec970b68a93a2a28bad1be Author: Richard Biener <[email protected]> Date: Wed Jul 8 13:57:17 2026 +0200 tree-optimization/126150 - ICE with replace_uses_by replace_uses_by triggers eventual BB removal from inside a FOR_EACH_IMM_USE_STMT iteration. That's a no-go since we might eliminate uses in the list we are currently processing. The fix is to defer EH edge purging. PR tree-optimization/126150 * tree-cfg.cc (replace_uses_by): Delay purging of EH edges until after FOR_EACH_IMM_USE_STMT finished. * g++.dg/pr126150.C: New testcase.
