Please write in English if possible, because the Emacs maintainers
usually do not have translators to read other languages for them.

Your bug report will be posted to the address@hidden mailing
list.

Please describe exactly what actions triggered the bug
and the precise symptoms of the bug:

I think I was trying to save a file.  I reported a similar
problem a couple of weeks ago and was eventually convinced
it may have been due to a disk problem.  However, I am now
getting it on a different machine (both are
relatively new intel iMacs).

This is a moderately frequent error this afternoon.

The output from debug is this:
Debugger entered--Lisp error: (range-error "floor" 175114285880178.06)
  floor(175114285880178.06)
  timer-relative-time((17599 53421 847094) 0.5 0)
  timer-inc-time([t 17599 53421 847094 0.5 blink-cursor-timer-function nil
nil] 0.5 0)
  timer-event-handler([t 17599 53421 847094 0.5 blink-cursor-timer-function
nil nil])

The output from gdb is this:
