gdb backtrace

$ 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.
Comment 1 Ville Skyttä 2016-01-26 04:22:09 EST
(Oops, it's Ctrl+\ I'm sending that triggers the coredump, not Ctrl+@)
Comment 2 Michal Hlavinka 2016-01-28 04:33:57 EST
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. """
