Print stack trace of a core file without needing to enter gdb interactively

For automated unit tests I wanted my program to run normally, but if it crashed, to add a stack trace to the output log. I came up with this command so I wouldn't have to mess around with core files. The one downside is that it does smoosh your program's stderr and stdout together. Show Sample Output
14gdb -batch -ex "run" -ex "bt" ${my_program} 2>&1 | grep -v ^"No stack."$ -
This does almost the same thing as the original, but it runs the full backtrace for _all_ the threads, which is pretty important when reporting a crash for a multithreaded software, since more often than not, the signal handler is executed in a different thread than the crash happened.
6gdb --batch --quiet -ex "thread apply all bt full" -ex "quit" ${exe} ${corefile}

Any thoughts on this command? Does it work on your machine? Can you do the same thing with only 14 characters?
