- Optionally, Emacs can generate a @dfn{core dump} when it crashes. A
-core dump is a file containing voluminous data about the state of the
-program prior to the crash, usually examined by loading it into a
-debugger such as GDB@. On many platforms, core dumps are disabled by
-default, and you must explicitly enable them by running the shell
-command @samp{ulimit -c unlimited} (e.g., in your shell startup
-script).
