Does your RVV implementation expect out to be 32 byte aligned? Because
looking at aaccoder.c, quant_bands() is called with AACEncContext.qcoefs
as argument for out, which is 16 byte aligned.
Even if your implementation can work with 16 byte alignment, IMO the
alignment of qcoefs should be bumped. That way we can add an AVX version
too.

The RVV code requires 32-*bit* alignment for all pointers, i.e. natural alignment for int and float. I will fix the test case.
(IMO 32 byte alignment is counter-productive on non-x86, but that's a more general problem.)
