Comment(by simonmar):

 You could make the program even simpler by passing the result to a
 foreign-imported C function to print it out, instead of using `showHex`.
 Then you would be using no library code at all, and you should be able to
 trace through the assembly to figure out where something has gone wrong
 (unfortunatey I don't read PPC assembler so I'm no use here).
