bug#24959: 26.0.50; cancel-timer: void-variable timer

[Oleg Sivokon]

Lars,

Simplified version looks like this:

(setq timer (run-at-time 1 1 (lambda () (cancel-timer timer)))

The version that does work looks like this:

(let ((timer [nil]))
  (aset timer 0 (run-at-time 1 1 (lambda (timer) (cancel-timer (aref
timer 0))) timer))
