--- Comment #8 from GCC 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:33ead6400ad59d4b38fa0527a9a7b53a28114ab7 commit r15-2431-g33ead6400ad59d4b38fa0527a9a7b53a28114ab7 Author: Richard Biener <rguent...@suse.de> Date: Wed Jul 31 10:07:45 2024 +0200 middle-end/101478 - ICE with degenerate address during gimplification When we gimplify &MEM[0B + 4] we are re-folding the address in case types are not canonical which ends up with a constant address that recompute_tree_invariant_for_addr_expr ICEs on. Properly guard that call. PR middle-end/101478 * gimplify.cc (gimplify_addr_expr): Check we still have an ADDR_EXPR before calling recompute_tree_invariant_for_addr_expr. * gcc.dg/pr101478.c: New testcase.
