Example: $ echo !() should print the contents of the current directory, but actually makes bash hang with 100% CPU usage. Also affects other pattern types, e.g. @() and ?(). Non-empty patterns work correctly. After executing a command containing such a glob, a SIGKILL is required to terminate the process.
