It does look like it disappeared in GCC 10.0 after g:6889a3acfeed47265886676c6d43b04ef799fb82 AKA r275981. Thanks for the heads up! Let me add the test case and resolve the 10 regression as fixed (r275981 was checked in to fix a false negative, not specifically suppress a false positive, but it fixed a bug that apparently worked ways). Since the fix adds new warnings I don't think the policy allows it to be backported to GCC 9.
