Subject: 28.0.50; run-with-idle-timer (maybe) panic randomly on mac

[Message part 1 (text/plain, inline)]

I use run-with-idle-timer to make a auto GC timer in my init file. However,
on macOS 10.15.2, my emacs randomly panic for no reason. I guess it make
be some problem happens in auto GC configuration. Then I comment those
block of code, my emacs doesn't panic after I comment those block of
code.

Here is my init configuration of GC:

```lisp

(defmacro k-time (&rest body)
  "Measure and return the time it takes evaluating BODY.”
  `(let ((time (current-time)))
     ,@body
     (float-time (time-since time))))

;; Set garbage collection threshold to 1GB.
(setq gc-cons-threshold 1000000000)

;; When idle for 15sec run the GC no matter what.
(defvar k-gc-timer
 (run-with-idle-timer 60 t
 (lambda ()
 (message "Garbage Collector has run for %.06fsec”
 (k-time (garbage-collect))))))
```
