Question

I’m using ncurses and whenever I get a segfault, ncurses doesn’t properly release control of the terminal (because endwin() was never called). I set up a signal handler:

void handler(int signum) {
    endwin();
    exit(EXIT_FAILURE);
}

but the problem with this is that the segfault is ignored, as opposed to delayed until after endwin(). I’m fairly new to C++; can segfaults be caught like exceptions, so that I could have a finally block? Or is there someway to resend the segfault from inside the handler?

Answer 1

Segfault is undefined behavior. You must find it and fix it. Don’t worry about ncurses not releasing the terminal, and find and fix the bug.
