Replying to [comment:4 Lennart]:
> This is probably due to memory Haskell allocation not respecting the
alignment asked for by Storable. But I think that's been fixed now.
If it was using one of the array allocation operations, such as
`allocaArray`, then I only just pushed the patch that uses alignment for
these. So it might work now. The remaining place that we're not using
alignment constraints is `malloc`, but I ''think'' this should be ok -
`malloc` is supposed to give you memory that is aligned to the greatest
degree required by any native data type.
