Run GDB in a loop until hitting an error

So you have a bug that only happens sometimes and you need to inspect it in GDB? One way to do it would be to start the program then manually do run each time it ends until you hit the error.

  set pagination off
  b _exit
  commands
  run
  end
  

• Type run and enter to start the first run
