Hi,
I wanted to know if any porting is available for back trace implementation for uclibc in arm that I can use in my signal handler to debug segmentation faults.
I did come across a useful code here and tried using it inside my signal handler but it fails at the first check and returns from there.
I also tried a recurcive backtrace function which simply recursed using (current_frame_p)-3) till it was NULL and printed (current_frame_p)-1). This too seems to give me issues. All I get is the address of the handler and some garbage big address (I assume it might be the signal address). But I don't go beyond that. I want my trace to go beyond that.
The code that crashes is purposefully written for debug to dereference and invalid address.
Any help will be much appreciated.
Many many thanks in advance.
