Hello GAP Forum:

Is the following behavior a bug?

gap> S:=PolynomialRing(Rationals,["x"]);
<algebra-with-one over Rationals, with 1 generators>
gap> p0:=UnivariatePolynomial(Rationals,[1,1,1,1,1,1,1,1,1,1],1);
1+x+x^2+x^3+x^4+x^5+x^6+x^7+x^8+x^9
gap> p0:=UnivariatePolynomial(Rationals,[1,1,1,1,1,1,1,1,1,1,1],1);
1+x+x^2+x^3+x^4+x^5+x^6+x^7+x^8+x^9+x^10
gap> C11:=FieldExtension(Rationals,p0);
<field in characteristic 0>
gap> IsAbelianNumberField(C11);
value property is already set the other way at
SetIsPrimeField( P, true );
PrimeField( F ) called from
<function>( <arguments> ) called from read-eval-loop
Entering break read-eval-print loop, you can 'quit;' to quit to outer
loop,
or you can return to set it anyhow to continue
