--- Comment #5 from Jakub Jelinek <jakub at gcc dot gnu.org> --- (In reply to Martin Sebor from comment #4) > The problem is fixed by the patch for PR 91582: > https://gcc.gnu.org/ml/gcc-patches/2019-12/msg00478.html That patch doesn't even mention the compute_objsize changes that matter most for this in the ChangeLog entry. The sign_mask > 0 case which is never possible is still in there etc.
