Ticket #13705 (new defect)
segfault in analytic_rank(algorithm='rubinstein')
|Reported by:||dimpase||Owned by:||cremona|
apparently, PARI ungracefully runs out of memory on the following:
sage: e= elliptic_curves.rank(8) sage: e.analytic_rank(algorithm='rubinstein') *** Warning: not enough memory, new stack 18446744073268923520. ...[lots of similar lines removed] *** Warning: not enough memory, new stack 17179869183. *** Warning: *** bug in PARI/GP (Segmentation Fault), please report *** bug in PARI/GP (Segmentation Fault), please report ...[lots of similar lines removed]
certainly, this is a difficult elliptic curve to deal with, but still, segfault is a segfault. See the related sage-devel discussion.
