the testcases that randomly pass or fail check the dump files to make 
sure that specific transformations have been performed.  So i guess you 
could say that it is a missed optimization but given that this is most 
likely caused by either storage being overwritten or an uninitialized 
variable, it is hard to assure that this does not effect correctness.
