New description:
Here is an explicit example:
{{{
sage: var('x')
sage: K=QQ.extension(x,'x')
sage: (K*(1/4)).intersection(K*(1/4))
Fractional ideal (1/16)
}}}
----
Apply [attachment:10767_doctest.patch] to the Sage library.
(The issue is fixed by #11130, upgrading PARI, but the patch adds a
corresponding doctest, so this ticket is '''not''' a duplicate.)
