Thanks for replies

1. As explained in first post of thread , using normal gdb backtrace comand could not helpful , since i know Segmentation fault log , my question is not how i could catch the segmentation fault error log or fix it , since i know how.
my question is , If segmentation fault error occur more than 12 times , my environment (or maybe my kernel would crash) it could be kernel bug with my stb , Therefore , using -g and catch the first SEGV is not my desire (i know even the fix for this SEGV) but i deliberately , let it to be , in order to investigate Kernel (or environment) crash

if i use -g option and use gdb , before i could achieve to investigate Kernel (or environment) crash , i would get Segmentation fault (which is not as my desire , since it prevent me to know , why kernel would crash...


2. i compiled polo , with the cc option : -ggdb
could somebody please tell me what is the difference beetween -g and -ggdb in cc option?

NAME
abrt-action-analyze-backtrace - Analyzes C/C++ backtrace, generates duplication hash, backtrace rating, and identifies crash function in problem directory DIR. SYNOPSIS
abrt-action-analyze-backtrace [-v] [-d DIR] DESCRIPTION
The tool reads a file named backtrace from problem directory, generates duplication hash, backtrace rating, and identifies crash function. Then it saves this data as new elements duphash, rating, crash_function in this problem directory. Integration with libreport events abrt-action-analyze-backtrace can be used as a secondary analyzer, after backtrace has been generated. The data generated by abrt-action-analyze-backtrace is useful for reporting the crash to bug databases: rating makes it possible to prevent reporting of bugs with low quality (non-informative) backtraces, duplication hash is used to find already filed bugs about similar crashes. Example usage in report_event.conf: EVENT=analyze analyzer=CCpp abrt-action-generate-backtrace || exit $? abrt-action-analyze-backtrace OPTIONS
-d DIR Path to problem directory. -v Be more verbose. Can be given multiple times. AUTHORS
