Hi,

I cannot reproduce, I get with revision 9d69b04:

zimmerma@coriandre:~/svn/cado-nfs$ ./cado-nfs.py
191907783019725260605646959711 -dlp -ell 101538509534246169632617439 -gfpext 2
...
Info:Complete Factorization / Discrete logarithm: The polynomial defining the
finite field is 1,-61096303626605014149726703721,1

Please can you give us more details (version of CADO-NFS used, hardware,
operating system, compiler)?

Best regards,
Paul Zimmermann
