Funny enough, 32 bit Vista doesn't care if zero[0] is 0 or a - non-0 count value, while older versions of Windows might crash if - zero[0] is set to a non-zero value, as observed at least on XP 64. + instead. 32 bit Windows and former WOW64 don't care if zero[0] is 0 + or a sensible non-0 count value.
