Right; I was unclear earlier. This bug should only appear on 32 bit Pythons.
On Pythons with 64 bit integers, these are not long integers and have no L
suffix.
This is basically a bad behavior for the hex() function, and I believe this was
*intended* to be fixed in Python 2.x, but was accidentally missed and now is
only fixed in Python 3. The solution for us is to use "0x%x" % (n,)) or
hex(n).rstrip("L") or something instead of the plain hex(n). We'll push a fix
for this at some point.
Thanks again for pointing out the problem.
