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.
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
