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

[From: Han]

no problem. Thanks. I learned about strace and OOM killer.  It turns
out it's due to memory leaks. There are many leaks reported by
Valgrind. I fixed those that are clearly my fault and now my program
running on 770 without crash :-).   Thanks for this mail alias !  -
