For the rank $8$ elliptic curve with a-invariants $(0, 0, 1, -23737, 960366)$ sage 5.3 reports analytic rank $4$ in about 2.4 hours.

Almost sure this a bug, so I am interested what other CAS say on the matter of
the analytic rank. Currently testing pari's *ellanalyticrank()* but I have the impression
sage is several times faster than pari on this problem.

What CASes say about the analytic rank of '457532830151317a1'?

(It might be a good idea to verify my results, I ran them twice).
