How do you think we can fix the "excessive stack usage"?

----------------------------------------
Feature #13637: [PATCH] tool/runruby.rb: test with smallest possible machine stack
https://bugs.ruby-lang.org/issues/13637#change-65906

* Author: normalperson (Eric Wong)
* Status: Closed
* Priority: Normal
* Assignee: 
* Target version: 
----------------------------------------
Lets ensure none of our C functions use too much stack space and
fix all excessive stack usage before releasing the next version.
Reducing C stack usage should reduce conservative GC scanning
time and improve performance.

Hopefully there are no objections; I will commit in a few days.

If there are platform-dependent CI failures; excessive stack
usage should be fixed; rather than increasing minimum values or
removing these envs from testing.
