Memleak in multi_polynomial_libsingular.pyx — at Version 1

Description (last modified by jpflori)

Using the following piece of code makes the memory footprint of sage
grow indefinitely:

sage: K = GF(1<<50,'t')
sage: R.<x,y> = PolynomialRing?(K)

sage: a = K.random_element()
sage: while 1:
....: R(a)

So there is some memleak while creating elements of multivariate polynomial ring implemented with libsingular.

See for further discussion.
