Dear User
   I am working on a paper in a Debian Linux 64 bit. I have to advise you that the same program on a 32 bit work fine. But when I run it on a 64 bit I get a lot of
Segmentation Fault and problem in Maximization. Here I report a stange output that I got just fee minutes ago.

 

I start form the iteration number 30 of MaxBFGS
