Comment:
Having applied all the patches, I'm getting:
{{{
sage: R.<x> = QQ[]
sage: S.<a> = R.quotient(3*x^3 + 3/2*x -1/3)
sage: 3 * a^3 + S.modulus()
Error: unable to alloc/realloc memory
/home/ghitza/sage-devel/local/bin/sage-sage: line 206: 13092 Aborted
(core dumped) sage-ipython "$@" -i
}}}
(This is a doctest in
{{{rings/polynomial/polynomial_quotient_ring_element.py}}}, which is how I
ran into it.)
I don't know if it matters, but this is happening on a 32-bit machine.
