### Description

The following piece of code leaks memory.

sage: K = GF(1<<55,'t')

sage: a = K.random_element()

sage: while 1:

....: 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
