The reason for the assert is that the alignment is part of the
ABI of the types and is relied on when using LDR and STR for
some moves. Even though -fpack-struct=N changes the ABI in general,
I don't think it should change it in this particular case.
I have to wonder why GCC even has -fpack-struct= though. Do you have
a specific need for it, or was this caught by option coverage testing?
If there is no specific need, I'd be tempted to make -fpack-struct
unsupported for AArch64. I think there are so many other things
that could go wrong if it is used.
