IIRC, yes when using the GC, as that only guarantees 16-bytes
alignment. Static arrays on the stack should be aligned

Found one, I'll see if I can fix the array runtime:

All blocks in the GC that are more than 16 bytes are aligned by

each element is 32 bytes long.

`hashtrack filter` is supposed to be valid, then filter isn't
