The reason why x86 does not have this problem is because the schedular does not move around 
load and stores as much as the PPC schedular does, look at the gcc which is SPEC, it contains non 
alias safe code and it passes comparison test using the pentium 3 schedular but not with the G4 
PPC one, it fails.  Another reason why it effects PPC linux only and not PPC darwin is that the PIC 
code generation is different so you get different code for the PIC code, it might effect PPC darwin 
(in fact the simplified testcase does seg fault on PPC darwin).  So the scheduling of the asm causes 
the load at different times.
