2010 Homework No. 3 - findsuss

Write a program in the language of your choice that takes a string and inputs "SUSSMAN" for every time those characters appear. In case I'm not being clear, that means output "SUSSMAN" for every 3 's's and 1 'u', 'm', 'a', and 'n' in the string. Inputting "ssssumanssssssssssuman", for example, would print "SUSSMAN" twice. "ssuman", however, would print nothing.

I've written an inelegant solution in C, which I'll post in a second. It tends to crash after execution, however, and I cannot for the life of me figure out what I'm doing wrong. It does everything it's supposed to but refuses to terminate politely. Even stranger, it only happens when there is enough characters for two or more sussmen. I guess the problem is in the susscount loop, but I can't figure out where. Mind giving me a hand, /prog/?

The homework series was less bad back when it was not done by the guy appending numbers to it.
