You're allocating the memory to store listener_encoding in ircd_parser.y,
then passing a pointer to this memory down to add_listener().  At this
point, add_listener() should create its own copy of it and use that in the
listener, but youre instead setting it to whats been allocated in
ircd_parser.y.  As soon as you get another listener_encoding, this memory is
free()'d - except youve still got a pointer to it in your listener struct.

Your listener should allocate its own copy of the encoding.

I'd also advise you dont use strcpy() unless youre *absolutely* sure that
youre never going to get an overflow.  Use strlcpy() instead.
