The `mdb -k' dcmd ::nce will segfault when run multiple times
The problem is that in the nce dcmd opt_ill is not initialized and mdb_getopts does not change the value of opt_ill. This means that if it's stack garbage, we'll end up hitting driving on and dereferencing what could be potentially garbage, if we're lucky.
