Emacs crashes

[Markus Rost]

Emacs on CVS crashes for me every other day or so.  Below are
backtraces from two of those crashes.  This is in

GNU Emacs 21.3.50 (sparc-sun-solaris2.9, X toolkit) of 2003-02-16 on arc
configured using `configure '--prefix=/home/rost/local' 
'--without-toolkit-scroll-bars''

In many if not all of the crashes the related auto-save-file (like
.saves-15321-arc~) is corrupted:  It consists of a couple of empty
lines, no other characters than new-lines in it.  No way to use
recover-session after the crash.  Maybe this is related, maybe not.
