Comment (by Bouillaguet):
Fine. This looks like a serious bug in PARI, because the determinant still
exists even though this specific algorithm cannot compute it...
So : modify the patch so that it chooses the threshold to call PARI
according to the length of the machine word, and we're good to go.
