    i just managed to get an sh coredump with an rc.d/ script of mine.
    here is part of the output of /etc/rc.d/test stop :

    /etc/rc.d/test: DEBUG: run_rc_command: evaluating :().
    Loading configuration files.
    Node type = 15
    pid 5183 (sh), uid 0: exited on signal 11 (core dumped)
    zsh: segmentation fault (core dumped) /etc/rc.d/test stop

    the 'Node type' message comes from sh's eval.c function. my rc.d/test
    is attached.

    the shell dies after the last command from test_stop(), but before the
    next command from run_rc_command(), as far as i can tell.

    what i want to do is basically the same that is done by
    rc.shutdown: going through rc.d/ in reverse order and calling every
    script with a 'stop' argument. my code is almost the same as in
    rc.shutdown. if i run test_stop manually (i.e. not through
    run_rc_command "$1" at the bottom of my script), everything seems to
    work just fine.

    can someone help me with this?

    thanks, t.
