Hi, Here's an annoying bug in an edge case. It appears that PARI (the QQ case below) computes the resultant correctly for a constant polynomial with itself and NTL (the ZZ case below) computes it incorrectly. I'm not really sure what the correct fix would be. I guess it's a small bug in NTL, but I haven't looked at that code yet. Should I be fixing this in NTL (eek, I haven't touched that code!) or making a special case?
