Re: nfgaloisconj() bug


it turned out to be a partial fix, because still:

? nfgaloisconj(nfinit(x^3-x-1),1)
  ***   bus error: bug in GP (please report).

Also, I noticed another thing, that goes back at least as far as

? nfgaloisconj(nfinit(x^4-2*x^2+9),0)
[x, 1/3*x^3 - 2/3*x, -1/3*x^3 + 2/3*x, -x]
? nfgaloisconj(nfinit(x^4-2*x^2+9),2)
[x, 0, 0, -x]

Correct me if I'm wrong, but from reading documentation, I don't see a
reason why the output should depend on the flag.  Or are these 2
output isomorphic to each other?
