--- Comment #2 from Andrew Benson <abensonca at gcc dot gnu.org> --- (In reply to Dominique d'Humieres from comment #1) > Confirmed. For me it segfaults from GCC7 up to GCC11. Interesting. This started occurring for me when I updated from GCC10.1 to 11. But, the code I posted is a reduced test case that I created - so maybe the original (non-reduced-test-case) code wasn't triggering this previously for some reason.
