calculating elliptic curve order gives pari error #12403
Comments
comment:1
The documentation for pari's ellap function says that it can handle primes up to 200 digits with the seadata package installed, which Sage does; and this prime has 115 digits. I can compute the cardinality of this curve in gp directly, but only after increasing the stacksize to 32000000. Sage starts with it at 16000000, which seems to be the problem -- though of course this should be caught, say within a try/except block. However, using Sage-4.8:
which is a rather serious bug. I will report that separately. |

Just an observation: I get the same error with

With Sage 5.9 I get
and I wonder if this still happens with the new pari version currently being tested? |

I guess the original problem is due to the fact that the optional Closing as invalid unless somebody convinces me that there is still a bug here... |
