Good !
About the original memleak, I tried looking at how
EllipticCurves_finite_field (maybe not correct name) are created but
could not find anything fishy, only Python code which should not
produce any memleak.
Hi
I think this is a problem with multivariate polynomials over finite
fields and is not specific to elliptic curves. The following code
produces a leak:
K=GF(2^50,"t")
R.<x,y>=PolynomialRing(K)
a=K.random_element()
while(1):
f=a*x
del f
When constructing an elliptic curve its equation is constructed in the
3-variable polynomial ring over K, and thus we will get this leak.
Best wishes
