New description:
Using the following piece of code makes the memory footprint of sage
[[BR]] grow indefinitely:
{{{
sage: K = GF(1<<50,'t')
sage: R.<x,y> = PolynomialRing(K)
sage: a = K.random_element()
sage: while 1:
....: R(a)
....:
}}}
The memleak happens when different si2sa_* functions are called.
