apparently, PARI ungracefully runs out of memory on the following:
{{{
sage: e= elliptic_curves.rank(8)[0]
sage: e.analytic_rank(algorithm='rubinstein')
*** Warning: not enough memory, new stack 18446744073268923520.

}}}
certainly, this is a difficult elliptic curve to deal with, but still,
segfault is a segfault. See the related
