<div dir="auto">I use run-with-idle-timer to make a auto GC timer in my init file. However,<br />
on macOS 10.15.2, my emacs randomly panic for no reason. I guess it make<br />
be some problem happens in auto GC configuration. Then I comment those<br />
block of code, my emacs doesn't panic after I comment those block of<br />
code.<br />
<br />
Here is my init configuration of GC:<br />
<br />
```lisp
<div dir="auto"><br />
(defmacro k-time (&amp;rest body)</div>
<div dir="auto">&#160; "Measure and return the time it takes evaluating BODY.”</div>
<div dir="auto">&#160; `(let ((time (current-time)))</div>
<div dir="auto">&#160; &#160; &#160;,@body</div>
<div dir="auto">&#160; &#160; &#160;(float-time (time-since time))))</div>
<div dir="auto"><br /></div>
<div dir="auto">;; Set garbage collection threshold to 1GB.</div>
<div dir="auto">(setq gc-cons-threshold 1000000000)</div>
<div dir="auto"><br /></div>
<div dir="auto">;; When idle for 15sec run the GC no matter what.</div>
<div dir="auto">(defvar k-gc-timer</div>
