Greetings,
In my experience, segmentation faults are *usually* due to memory
errors. When a program tries to access memory, and it is not permitted to do
so, a segmentation fault occurs. There are other possibilities, however this
has been the most-common source of the problem. As for troubleshooting at
this stage, I'm hoping someone else will jump in about now...
I just wanted to shed some light on the error quickly.
Regards,
Joshua
