[maemo-developers] how to get crash stack trace in Maemo 2.2 (Nokia 770)

[From: Han]

Hi,
I am using Maemo 2.2 to develop some programs for Nokia 770. Things
run pretty well except sometime my program would crash for unknown
reason. Normally I start the program from x terminal, and  it would
crash with only message "Killed".

I am wondering if possible to get a stack trace when the program
crashes?  so that I can find out where the crash happened in the code.

I tried to reproduce the issue with i386 in scratchbox, but did not
repro yet...

thanks
Han
