(Oops, it's Ctrl+\ I'm sending that triggers the coredump, not Ctrl+@) This is expected behaviour. http://www.gnu.org/software/libc/manual/html_node/Termination-Signals.html """ 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. """ |
