Comment(by fbissey):
With python-2.6:
{{{
sage: n=2^63+2^13
sage: n
9223372036854784000
sage: int(n)
9223372036854784000L
sage: hash(n)
-9223372036854767616
sage: hash(int(n))
-9223372036854767616
}}}
with python-2.7
{{{
sage: n=2^63+2^13
sage: n
9223372036854784000
sage: hash(n)
8192
sage: int(n)
9223372036854784000L
sage: hash(int(n))
-9223372036854767616
}}}
Furthermore in both case:
{{{
sage: type(n)
<type 'sage.rings.integer.Integer'>
sage: type(int(n))
<type 'long'>
}}}
So I would expect different hashes naively.
