[JDEV] Yahoo Transport Crash

[Kevin Limperos]

Hi,
	I'm running the Yahoo transport in its own (separate) jabberd on RH
6.2/Jabber1.4.1/Yahoo0.8-1.4. When a user logs in then logs out and logs in
again, something is apparently not reset or cleaned up correctly, as the
server core dumps. The trace is:

#0  0x8056fd1 in jid_cmp (a=0x30, b=0x81810c8) at jid.c:231
231         if(_jid_nullstrcmp(a->resource, b->resource) != 0) return -1;
(gdb) bt

Line 259 in presence.c:
  s = yahoo_find_session(yjp->yti, jp->from);

sets s to a value such that, s->online_users, while not NULL, seems to be
corrupted (value 0x30 above).

Any help would be appreciated. Thank you.
