I think there is no easy way of finding out where the 
optimization goes wrong. But should this happen at all, i.e. does 
it point to a flaw in my program or is it a compiler bug? I like 
to think it's the latter, after all the program works perfectly 
without -O. On the other hand, it's scary because I have no clue 
where to look for the offender.
