Try to squash 3 identical scanbuild warnings
I think scanbuild is deciding that 'depth' could be less than 0, leading
us to not enter the loop which assigns 'obj'. This is not true, the
depth cannot be less than 0.
Try making 'depth' an unsigned int as a hint to scanbuild, and see if
the warning goes away.
