regression in ZX_resultant_all() 

Hi,

it can be reproduced by the following:

? polgalois(subst(x^8-n*x^6+(2*n+14)*x^4-n*x^2+1,n,600!))
[40320, -1, 50]

It stopped working Nov 6, 2002.  ZX_resultant_all() returns a number
which is not a square, and galoisbig() thinks the group is ODD.

Thanks

Igor
