Hi,
regarding the problem of number fields defined by polynomial with
rational coefficients (http://trac.sagemath.org/sage_trac/ticket/252), I
implemented a simple patch that justs prints a warning at :
http://trac.sagemath.org/sage_trac/ticket/14146
However, I don't understand why this patch causes failures on some
machines, and not on others (see the patchbot results).
Cheers,

I'm fairly sure the problem is that the defining polynomial for the
relative extension is not monic. One solution would be to use an
equivalent monic polynomial and keep track of a simple transformation
allowing one to translate between the internal representation of
elements on the one hand and print representations and conversions from
polynomials on the other.

Hi all,
Adrien Poteaux reported this bug
(http://trac.sagemath.org/sage_trac/ticket/14146) to me. When you
create a number field (possibly on top of another number field),
what are the restrictions on the defining polynomial ? Currently,
strange PARI error occur, that are quite cryptic. Apparently,
At the very least, these restrictions (if they actually exist)
should be (better) documented...
Thanks,
