It could be application error i.e. it's not 64-bit big endian clean or
compiler problem. If you compile your application without optimization and
it will work then it's compiler failure and you can try to use newer gcc.
3.1 for example. Otherwise, debug your app.

Also it would be interesting to see what instruction causes misalignment.
