Ok so the memleak comes from ZZ_pE_to_ZZ_pX in

It should have been fixed by trac #1092, but has been reverted by

I'll reopen #1092.

S the memleak seems to be located within creation or rather coercing
to MPolynomial_libsingular.
Calling gc.collect() whithin the loop seem to fix or are least
attenuate the problem.
However, calling afterwards does not free memory back.

FYI, the interface to Maxima changed in 4.7.1.alpha0 IIRC, so you
could also try one of the more recent alphas available at:

The things with MARKER are not involved in that new interface.

Dear all,
Using the following piece of code makes the memory footprint of sage
grow indefinitely:
sage: K = GF(1<<50,'t')
sage: j = K.random_element()
sage: while 1:
:E = EllipticCurve(j=j)
:del E

This seems to be less dramatic with finite fields of char != 2 and
inexistant
This is now Trac #11390.

Adding

cdef GF2X_c r = GF2X_IrredPolyMod(GF2E_rep(self.x),GF2E_modulus())
fixes everything.

You were right, there is something wrong with the libgfortran file

I can confirm it fixes the bug, I'll add myself as a reviewer on Trac.
If I understand correctly, originally, __copy__ function of

__init__ function (without argument ? but I don't know which ?) so
_gobj is not initialized.

Hi Burcin,
Thanks for your quick answer!
I've got some other questions:
- Sage and pynac do not realize that 2^(-b_0) and (2^b_0)^(-1) are
equal.
I guess there is no canonical way of expanding 2^(a*b) into something
else, but it could be a good idea doing it when a or b is an integer
and the othe
ent changes are similar in both git repositories,
but as I was going through the source code, I saw that
numeric::do_print_csrc is defined in GiNaC but not in pynac.
