After this crash I updates my Emacs sources from CVS and recompiled.
I then tried again to file the new messages, again using a keyboard
macro.  I carefully hit "C-x e", which worked.  I then hit 'e' a few
more times, slowly, and it filed a few more messages correctly.  I
then held the 'e' key for a second to file a bunch more and again
Emacs crashed.  This time the backtrace looked like this:

Perhaps 'safe_bcopy()' needs to be renamed?

Program received signal SIGSEGV, Segmentation fault.
