Ok, ok, ok.

I wasn't very clear.

In the world structure, the dir_option[direction] consists of more than
just a target room.  For example, door names, door flags, and the string
sent to the player when they look in the direction.  The to_room of an
exit can be NOWHERE, and yet some of the remaining data still exist in the
directory structure--namely, the exit description.

If the exit doesn't exist at all (no strings, no flags, no door names, no
key, no 'to room'), you can't set data in it.  The MUD only allocates
memory for existant exits, so if the exit doesn't exist, you can't set
anything on it.

A way to fix this would be :
if (!world[rnum_of_room].dir_option[direction]) {
  CREATE(world[rnum_of_room].dir_option[direction], struct room_exit_data, 1);
  /* The `room_exit_data' is a fallacy.  The true room struct can be found
     in structs.h */
  ...initialize some vars...
} your stuff...
