bug using toField twice

[naddi...@gmail.com]

Dear All,

The following code generates an error, "internal error: ring element gcd computation failed," and then dumps core.

F = toField(QQ[i]/(i^2+1))
K = toField(F[r]/(r^4-2))
r^-1

I can work around it by doing

K = toField(QQ[i,r]/(i^2+1, r^4-2))

r^-1

but I thought someone might want to look into it.

Thanks,

Nick

It also runs fine if I omit "toField" everywhere:

F = QQ[i]/(i^2+1)
K = F[r]/(r^4-2)
r^-1
