Yes, segfault. Also, I would like to specify that it does not simply
happen if cop-adding whilst the engine is running, but also if the
engine has begun processing at all (as in stop/cop-add/start) and also
occasionally on copp-sets. So far, the only reliable way to avoid any
crash is to cop-add the plugin before any processing is done and leave
well alone.
