xemacs crash out of the blue

In XEmacs 21.4 (patch 12) "Portable Code" [Lucid] (i686-pc-linux) of Tue Dec 16 2003 on longmore
configured using `configure --prefix=/usr/local/sw/xemacs-21.4.12 --with-database=no'



Unfortunately I am not able to say,  what actually triggered the crash I
am reporting.  I was in the middle of a phone call,  when I suddenly saw
my XEmacs disappear with "Fatal error (11)."

It might give a clue that I am using gnuserv quite often.  Anyway,  here
is the only substantial information I gan give:
