The bug is in fact:
# 2147483648l;;
- : int32 = -2147483648l
and given that behaviour, the above result makes sense! But...

and it's outside the range [Int32.min_int, Int32.max_int]
However, it's a known bug - http://caml.inria.fr/mantis/view.php?id=4210
According to Mantis, it's fixed in 3.12 - I'm sure there's a reason that
it's not been fixed in 3.11.2+rc1
