We can't reproduce this, as we don't have g or i.  But the general 
advice in a case like this is to simulate the loop by hand:  write down 
what is in each of the variables, and walk through the loop.

I suspect your problem is in initializing count improperly, or in 
putting the test in the wrong place.
