Crash in either ircg_set_current or ircg_join when
running the IRCG sample scripts as produced by Sasha.

We've installed
  latest php4 CVS (as of 15 march)
  thttpd 2.20b
  st 1.0 and st 1.1
  IRCG 2.1
  hybrid ircd (on localhost port 6667)

The trace below may be misleading because of the threads
involved.

Program received signal SIGSEGV, Segmentation fault.

The following, perhaps, helps:
