--- Comment #26 from Sam James <sjames at gcc dot gnu.org> --- I can still reproduce it with r16-7666-gb67918fddab42c. It sounds a lot like PR123888 (wrong devirt target). I don't have any further testcase (not looked at it since a while). Was hoping for fuzzers to find some simpler testcase (but they generally do C for wrong-code sadly) or some package to fail that wasn't huge.
