Hi,

We are trying get call stack call by using "bt_get_backtrace()" API when there is a crash and we are able get the call 
stack but if we enable optimization levels(-O1 or -O2) during compilation, we are unable to get call stack. Can anyone 
could help us that is there any dependency(or)relation between getting call stack and optimization levels and please 
help us how to get call stack with optimization is enabled.

Thank you in Advance.....

Thanks & Regards,
Sai
