Replying to [comment:7 was]:
> One doctest fails on sage.math after applying the patch: [...]
it seems just a formatting issue, both outputs are equal (and I don't
understand why the 'expected'
one was split among several lines).
Note that I also had this problem with:
{{{
----------------------------------------------------------------------
| Sage Version 4.4.2, Release Date: 2010-05-19 |
| Type notebook() for the GUI, and license() for information. |
----------------------------------------------------------------------
sage: P.<x,y> = PolynomialRing(ZZ,2)
sage: f = x+y
sage: g=y^2+x
sage: f.resultant(g,y)
------------------------------------------------------------
Unhandled SIGFPE: An unhandled floating point exception occured in Sage.
This probably occured because a *compiled* component
of Sage has a bug in it (typically accessing invalid memory)
or is not properly wrapped with _sig_on, _sig_off.
You might want to run Sage under gdb with 'sage -gdb' to debug this.
Sage will now terminate (sorry).

}}}
Maybe we can just fix the doctest?
