[VANILLA-L:732] daemonII core dumps



We hosted an Australian Clue Game on netrek.syd.att.net.au today, and
experienced a core dump of daemonII every twenty minutes or so, usually
once we got to something near twelve players.

The back trace on the core dump is confusing ...

% dbx daemonII.5 core.5
dbx version 3.11.8
Type 'help' for help.
Core file created by program "daemonII"

signal IOT/Abort trap at >*[ctime, 0x3ff800e7a50]       ldq     r27,
-26800(gp)
(dbx) t
>  0 ctime(0x3ff80170a44, 0x3ffc0080c50, 0x3ffc0082590, 0x4, 0x3ff8010fb04) [0x3
ff800e7a50]
   1 _NLxcolu(0x3ffc0080c50, 0x2238, 0xa4f0a350a746967,
0x6e6972700a300a32, 0x11

   2 __addxp(0x0, 0x1, 0x0, 0x1c21, 0x0) [0x3ff80159f40]
(dbx)

Which suggests to me some form of stack corruption.
Any ideas for diagnosis?

(dbx) p *mctl
struct {
    mc_current = 60
}
(dbx) p messages[58].m_data
"GOD->ALL  Karaoke Bar (O1) was kill 1.56 for whizkid (Fb) [photon]"
(dbx) p messages[59].m_data
"Altair->FED We are being attacked by Quozl O4 who is 17% damaged."
(dbx) p messages[60].m_data
"GOD->ALL  Muad'Dib (O3) was kill 2.02 for Aurelius (F0) [photon]"

I'll check ERRORS and the other logs.
