It always crashes here. You cannot compare a value lower than 0 (>=0
may end to <0) if you use a unsigned integer. It may work in many
cases and be evaluated as true in many other (like in some  64bits
system + gcc).

I can give you another version which does not use any integer but
decrement the pointer until it reaches the beginning of string, it is
safe and platform independent.
