Building it with a recent GCC the code doesn't actually break with depth =3D 0, i.e. the comparison "0-- > 0" will exit the loop instead of proceeding, but 'depth' will retain the overflow value afterwards. This behavior can be compiler dependent, so change 'depth' to int to remove this potential ambiguity.
