'function' : recursive on all control paths, function will cause runtime stack overflow
Every path through a function contains a call to the function. Since there is no way to exit the function without first calling itself recursively, the function will never exit.
The following code demonstrates how this warning would be generated:
int func(int x) { if (x > 1) { return func(x - 1); // recursive call } else { int y = func(0) + 1; // recursive call return y; } } void main(){ func(1); }
