C isn't guaranteed to optimize tail-recursion, so you might get a stack overflow.

recursion means it loops forever means itit loops forever means it loops forever means it loops forever means it loops forever means it loops forever means it loops forever means it loops forever means it loops forever means it loops forever means it loops forever means it loops forever means it loops forever means it loops forever means it loops forever means it loops forever means it loops forever means it loops forever means it loops forever means it loops forever means it loops forever means it loops forever means it loops forever means it loops forever means it loops forever means it loops forever means it loops forever means it loops forever means it loops forever means it loops forever means it loops forever means it loops forever means it loops forever means it loops forever means it loops forever means it loops forever means it loops forever means it loops forever means it loops forever means it loops forever means it loops forever means it loops forever means it loops forever means it loops forever means it loops forever means it loops forever means it loops forever means it loops forever means it loops forever means it loops forever means it loops forever means it loops forever means it loops forever means it loops forever means it loops forever means it loops forever means it loops forever means it loops forever means it loops forever means it loops forever means it loops forever means it loops forever means it loops forever means it loops forever means it loops forever means it loops forever means it loops forever means it loops forever means it loops forever means it loops forever means it loops forever means it loops forever means it loops forever means it loops forever means it loops forever means it loops forever means it loops forever means it loops forever means it loops forever means it loops forever means it loops forever means it loops forever means it loops forever means it loops forever means it loops forever means it loops forever means it loops forever means it loops forever means it loops forever means it loops forever means it loops forever means it loops forever means it loops forever means it loops forever means it loops forever means it loops forever means it loops forever means it loops forever means it loops forever means it loops forever means it loops forever means it loops forever means it loops forever means it loops forever means _...

on my machine it hits kern.maxproc a long time before overflowing the stack could even start to be a problem.

Quit bragging about how big you're stack is, jerk
