Comment (by jpflori):
I could put my hand on a Mac OS X 10.7 where the problems occur.
At least one of the really worrying things is as follow:
* converting an integer coefficients poly to a rational coeffs one kill
all coeffs after any coeff whose size is larger than 64.stg bits.
* but they are not really killed as the poly is still aware of it degree
and you can still test equality of the original int poly with the new rat
poly and get True.
That's the problem behind all the factor() calls giving stupid results
(and maybe other failing doctests).
There seems to be a problem in the call to fmpq_poly_set_fmpz_poly in
polynomial_rational_flint.pyx at line 257.
