Umm, there is no such thing as infinite recursion. If you doubt that I'll make you a nice little C program that will keep recursing until it crashes. The runtime stack has a maximum size. Granted the size is pretty large, but it will crash if you exceed it. If you doubt what I say, here is an example from Microsoft that will lead to a stack overflow
