I haven't followed this thread in all its gory details, but I recall 
that only emacs-w32 was reported to have problems. I have noticed random 
crashes and weird messages without prior user actions in emacs-x11 since 
I moved from WinXP + Cygwin x86 to Win7 + Cygwin x86_64 a few weeks ago. 
None of these problems ever occurred on either FreeBSD (amd64, Emacs 24) 
or Debian (amd64, Emacs 23). I just thought I'd mention this because the 
problem does not seem to be limited to the -w32 build of Emacs. I've 
preserved the odd messages on three separate occasions:

Args out of range: [t 21335 39727 373923 0.5 blink-cursor-timer-function 
nil nil 100000], 4

Invalid function: #[(timer) "^H >^H
> ^[\211^203^Q^@Ã
^H	    \"^Q^K\203^Z^@Ã
\"^R^L\206^_^@^K*\207" [timer timer-list timer-idle-list cell2 cell1 
delq] 4 2245674]

timer-relative-time: Wrong type argument: vectorp, [t1 time high low 
micro pico nil 3 0 2 ...]

All of them indicate timer related problems as Max pointed out. I do not 
have meaningful backtraces of the crashes at this time because the 
installed emacs-x11 seems to lack debug symbols.

I'll grab the -x11 build of Ken's test release and see if these odd 
messages and crashes still occur.
