abrt-action-generate-core-backtrace
ABRT-ACTION-GENERA(1) ABRT Manual ABRT-ACTION-GENERA(1)
NAME
abrt-action-generate-core-backtrace - Generates coredump-level backtrace
SYNOPSIS
abrt-action-generate-core-backtrace [-v] [-r] [-d DIR]
DESCRIPTION
This tool uses coredump from the file coredump and binary at the path stored in file executable in the problem directory to generate
coredump-level backtrace.
Coredump-level backtrace resembles ordinary backtrace in that it contains information about call frames present on the stack at the time of
the crash. However, it only contains information that can be obtained from the coredump without debugging symbols available - mainly
relative addresses of the stored instruction pointers. Such backtrace can still be useful for reporting and reproducing the bug and does
not require debugging information files to be installed.
The result is saved in the problem directory in a file named core_backtrace.
Integration with libreport events
abrt-action-generate-core-backtrace can be used as an analyzer for application crashes which dump core.
Example usage in report_event.conf:
EVENT=analyze analyzer=CCpp
abrt-action-generate-core-backtrace
OPTIONS
-d DIR
Path to problem directory.
-r
Do not hash function fingerprints. Useful for debugging.
-v
Be more verbose. Can be given multiple times.
