  3. Make debugging process stop.
    Make vifm crash.
  4. Redirect output of gdb commands to a file.
    Execute set logging file {out-file} in the command prompt of the gdb, where {out-file} can be for example: ~/
    Execute set logging on on the command prompt of the gdb to enable logging.
  5. Output back trace with values of all local variables.
    Execute bt full (backtrace full is full form of the command) in the command prompt of the gdb.
  6. Quit gdb.
    Execute quit command (or just q, or even ctrl-d shortcut) in the command prompt of the gdb.
  7. Upload file with the logged output of the bt command (e.g. ~/ somewhere (e.g. on bug tracker, or make a Gist or to pastebin) or send as an attachment to the maintainer (; please do not include it in the message itself as it might make it unreadable.
