Did you use -O >2 ? I dimly remember xlc docs saying that higher  
optimization levels enable 'potentially semantics changing'  
optimization strategies - maybe you just found such a case. Not sure  
if that was at -O2 or higher though, and the xlc in question was  
ancient - 5.0.2 or something like that.

have fun
