I have got my own bug.
Add the attribute may_alias to the (const unsigned int *) when creating the type will make sure 
there is no aliasing problems.
The 2 (short case) instead of 4 should be able to be done the same way and also the 8 case (long 
long).  I have to check on the size of the types but that is the only thing different than the 1 size 
case that is already there besides the extra attribute, I should be able to do this tonight.
