12928 critical bug in multivariate polynomial factorization over GF(2) Paul Zimmermann tbd "consider the following (both with Sage 4.8 and Sage 5.0.beta13 without {{{proof=False}}}):
{{{
sage: R.=GF(2)[]
sage: factor(x^6 + y^6 + x^5 + x^3 + x + 1,proof=False)
x^6 + y^6 + x^5 + x^3 + x + 1
sage: (x^4+y^2*x^2+x^2+y^2*x+y^4+y^2+1)*(x^2+x+y^2+1)
x^6 + y^6 + x^5 + x^3 + x + 1

This seems to be a bug in Singular factorization. I set the priority to ""critical"" since this is really a very basic routine.
