$ ncat localhost 80 # or some other port where something's listening
^\Quit (core dumped)
(The ^\Quit above is a result of pressing Ctrl+@)
gdb backtrace attached.
(Oops, it's Ctrl+\ I'm sending that triggers the coredump, not Ctrl+@)
This is expected behaviour.
""" The SIGQUIT signal is similar to SIGINT, except that it’s controlled by a different key—the QUIT character, usually C-\—and produces a core dump when it terminates the process, just like a program error signal. You can think of this as a program error condition “detected” by the user. """
