Please confirm that the system you were building this on was not low on memory. From reading the PARI sources, it looks like that message can only occur after a failed |

As I said its on mod, so a pretty beefy machine with 128GB ram. Of course I don't know exactly what happened, but I think its pretty unlikely that some runaway process ate everything except 2% of the available ram such that only this doctest failed. Twice in a row. |

Basically, every time you use lcalc to do anything with elliptic curve L-series, you get some mysterious warning (of course, really output from PARI). However, the problem has been in released Sage for a long time. It was in sage-4.7.
