polisirreducible and factor

[Jean-Marc Sac-Epée <jmse@poncelet.univ-metz.fr>]

I have strang problems with "polisirreducible" and "factor" functions,
which fail with some peculiar polynomial.

Let me give the following sample:

? p=x^44 + x^42 - x^31 - x^29 - x^26 - x^24 - x^23 - x^21 - x^20 -
 x^18 - x^15 - x^13 + x^2 + 1
%1 = x^44 + x^42 - x^31 - x^29 - x^26 - x^24 - x^23 - x^21 - x^20- x^18 - x^15 - x^13 + x^2 + 1
? factor(p)

I think that  polisirreducible and factor functions have problems with polynomials which are divisible by cyclotomic polynomials. Is it possible?

Best regards,

JM
