I'm not 100% sure about e.g. Ada. C is certainly not affected, for Fortran in theory some OOP code could be, would need to investigate. The testbox I've bootstrapped earlier version of the patch is gone, I vaguely remember only seeing the notes in g++.dg/ and libstdc++/ testsuites and not elsewhere, but that is not a proof that it can't happen. The only thing that is clear is that C doesn't have anything but field decls in aggregates and so can't be affected.
