I've been noticing the background timer giving odd messages from
emacs-w32 once in a while such as the following when not touching the

seconds-to-time: Arithmetic range error: "round", -0.0e+NaN
seconds-to-time: Arithmetic range error: "round", 0.0
The stack dump of a recent emacs crash report on this list seemed to
be in background timer code. Maybe we found something.
Have you tried the test release
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
\"^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.
You have to install emacs-debuginfo in order to get the symbols.
