--- Comment #1 from Jakub Jelinek <jakub at gcc dot gnu.org> --- I guess as a temporary workaround I could stick // { dg-additional-options "-ftrivial-auto-var-init=uninitialized" { target c++26 } } until this is fixed. That said, I'm afraid I have no idea what those tests want to test and why are the extra .DEFERRED_INIT calls (which eventually expand to memset) or what a problem for those.
