Probably. They need to return something compatible with max_align_t,
which I strongly suspect is 8-byte aligned on Android.

There is a concept of "extended alignment" in the C and C++ standards,
where the user may have to realign the results of malloc manually, or
presumably implement custom new operators. This mostly only applies to
things like AVX-512 vectors though.

Cheers.
