There are some situations, discussed here in the past, where
that kind of problem is common with many compilers. In
particular, there are potential problems if n is the
largest positive value for the kind of i. If that's the
problem, I wouldn't consider it a bug; perhaps less than
ideal behavior, but not a bug. (And, of course, I'm
assuming that the problem doesn't relate to illegalities
such as changing the value of i inside of the loop).
 
Or maybe you hit an actual bug; I'm sure that some of
the ones I hit were bugs. Just thought I'd mention the other
possibilities for balance.
