(gdb) run
Starting program: /usr/bin/gbx2 
[Thread debugging using libthread_db enabled]
Using host libthread_db library
"/lib/arm-linux-gnueabi/libthread_db.so.1".
ERROR: #45: File or directory does not exist
[Inferior 1 (process 12262) exited with code 01]
(gdb) 

bt gives the message no stack.

(I tried many different ways of running gdb and all give
same answer as above - including set args)

hmm.. not sure which file or directory its looking for.
