Why not? (Of course in this case it's strange.) But in general is
there anything in C that states that it's broken having (and refering
and assigning to) static variables in a recursive function?

Say I have this function:

void f(int i)
{
  static depth = 0;

  depth++;

  printf("f: depth = %d.\n", depth);

  if( 0 < i )
  {
    f(i-1);
  }

  depth--;
}

Wouldn't f(3) give a printout of 1, 2, 3, 4?


Right,
