Comment(by was):
Hi,
For the record, this change introduced a major bug into Sage, because
PARI's hash_GEN is itself buggy. For example, by playing with ideals in
Sage (code is complicated though...), I quickly got into this situation:
{{{
sage: n0
[11, 3; 0, 1]
sage: n1
[11, 3; 0, 1]
sage: hash(n0)
-7493989779944505307
sage: hash(n1)
-6341068275337658331
}}}
