I ran into something that seems rather odd and most likely erroneous.
As you can see from the command line, I was testing for GF and xGF
cases on a rather large Proth prime. It appeared to work properly
until near the end. Then it finished in a matter of a second or two.


Factor of GF(1832495,11)!!!! (1232842.226000 seconds)
This line was generated in less than one second of wall clock time.


The five following lines were reported as taking 0.016 - 0.0 seconds.


Any ideas on what happened?


My guess is that these GF/xGF tests need to be retested. But it
brings to question as to whether any of the earlier tests are
accurate.
