11521 Memleak when resolving the action of Integers on an Elliptic Curve jpflori robertwb "The following piece of code leaks memory. [[BR]] [[BR]] sage: K = GF(1<<55,'t') [[BR]] sage: a = K.random_element() [[BR]] sage: while 1: [[BR]] ....: E = !EllipticCurve(j=a); P = E.random_point(); 2*P;
The problem seems to occur while resolving the action of ZZ on E.
It does not happen if:
- one does not change the curve in the loop
- does P+P instead of a multiplication
