Error while running Msieve 1.53 with factmsieve.py

Hi,
I've tried to factor some integer using Msieve 1.53 with factmsieve using this tutorial. It worked fine for most of the intergers I tried.
But I'm having problems with 80, 85, 95, 105 digit integers :

- While factoring the 80 digits integer, it says : an error occurred during polynomial search. (files attached : 80.n <= the 80 digits integer, 80.txt <= the algorithm's output)

- While factoring the 85, 95 and 105 digits integer, it says : msieve has stopped working.

Does anyone know what's going on ? Thanks

What size inputs did you have success with?

It worked with : 50, 55, 60, 65, 70, 90, 100, 110 digits integer.
The 100 and 110 digits integer are from here, and I generated the others with OpenSSL.
