Program exits with return code 0 if all frames were shown without any errors. If some frames were shown, but there were some non-fatal errors, possibly causing an incomplete backtrace, the program exits with return code 1. If no frames could be shown, or a fatal error occured the program exits with return code 2. If the program was invoked with bad or missing arguments it will exit with return code 64.
