How to generate a stack trace when an app or program crashes?

For a no threaded application


gdb -q my-program

In batch mode 
gdb -q -batch -ex run -ex backtrace my-program
	

With args
gdb -q --args my-program
gdb -q -batch -ex run -ex backtrace --args my-program




For a multithreaded app


% gdb -q \
      -batch \
      -ex 'set print thread-events off' \
      -ex 'handle SIGALRM nostop pass' \
      -ex 'handle SIGCHLD nostop pass' \
      -ex 'run' \
      -ex 'thread apply all backtrace' \
      --args \
      my-program \
      arguments-to-my-program
