Comment:
All doctests work with version 4.7.2. Also tests of the following form
also work:
{{{
sage: R.<x>=GF(3)['x']
sage: (x^2+1).is_squarefree()
True
sage: (x^2+x+1).is_squarefree()
False
sage: R.<x>=ZZ[]
sage: R(x^2).is_squarefree()
False
sage: R(4*x).is_squarefree()
False
sage: R(2*x).is_squarefree()
True
sage: R(x^2+2*x+1).is_squarefree()
False
}}}
The bug appears to be fixed
