Uncaught RangeError: Maximum call stack size exceeded ios 13.3.1

[Alexufo]

In release this causes an error in the console Uncaught RangeError: Maximum call stack size exceeded, but in debug it works. (older versions of ios don't have this)

I checked stack size of safari 13.3.1:

  let i = 0;
  (function inc() {
    if(i % 100 == 0) { console.log(i); 	}
    i++;
    inc();
  })();

And got 6900 - which is the same number as the dektop browser but causes an error only on mobile

Debug mode might be avoiding the Safari limit by doing less inlining (so stack frames are smaller), but I'm not sure.

To work around this browser issue, you can try optimizing the relevant file with something other than -O3 (like -O2, 1, s, z, etc.). Marking functions as noinline can sometimes help too.
