--- Comment #2 from Jakub Jelinek <jakub at gcc dot gnu.org> --- Created attachment 48359 --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=48359&action=edit gcc10-pr94724.patch Untested fix. Wanted to create it efficiently, but by building the COMPONENT_REFs with non-final second operand the flags computed by build2_loc aren't final either (TREE_SIDE_EFFECTS, TREE_CONSTANT, TREE_READONLY).
