Here it goes (python 2.5 - 64bit):

>>> import gmpy, sys, operator
>>> sys.maxint
9223372036854775807
>>> gmpy.mpz(sys.maxint)
mpz(-1)
>>> operator.index(gmpy.mpz(sys.maxint))
-1
>>> sys.maxint+1
9223372036854775808L
>>> gmpy.mpz(sys.maxint+1)
mpz(9223372036854775808L)
>>> operator.index(gmpy.mpz(sys.maxint)+1)
0

I don't pretent to fully understand what's going on, but
gmpy.mpz(sys.maxint)==gmpy.mpz(-1) is more than suspicious :)
