--- Comment #3 from Romain Geissler <romain.geissler at amadeus dot com> --- Hi, While I initially flagged this as a regression in gcc 11, it's indeed a latent gcc bug which predates gcc 11. What makes it for my specific test case a regression is because now tuple use [[no_unique_address]] which seems to be already identified as creating ICEs in issues #96863 and #97804. Cheers, Romain
