For debugging purposes you can start with a `lighter' program.

In order for gdb to dump meaningful results the program must be compiled

Useful information about a processes can be found with:
* pmap, reports memory map of a process.
* lsof, lists opened files for a process.
* strace/ltrace, allows you to analyse system/function calls.
* cat /proc/PID, various info about a process.
thanks,
Daniel.
