--- Comment #2 from Richard Biener <rguenth at gcc dot gnu.org> ---
I can now only see the correct
t.C: In member function 'auto ah::aq(long int)':
t.C:4:28: warning: argument 1 null where non-null expected [-Wnonnull]
4 | return __builtin_memcpy(0, &aq_ai, aj);
| ~~~~~~~~~~~~~~~~^~~~~~~~~~~~~~~
<built-in>: note: in a call to function 'void* __builtin_memcpy(void*, const
void*, long unsigned int)' declared 'nonnull'
not sure what changed it. If I supply (void *)4 as destination I get

that resembles what you are seeing I guess.
