>SIGSEGV is a very important signal. It happens when your program tries to access memory that it does not have. An appropriate reaction might be to

    allocate more memory
    read some data from disk into that memory
    do something with garbage collcetion (but what? I'm confused about this still.)

What? Are there any Real World Programs which do anything other than print a stacktrace and exit? I don't think this person gets what a segfault is.
