I ran into this when using a single thread. You only need one > thread that triggers a GC to cause this, it just needs to happen to > happen during that thread. But that is a macOS only problem, because the default stack size is ridiculously small. The fix that got installed, OTOH, is much more general. If you want to make a macOS-only change that enlarges its stack we give to threads, I can live with that on emacs-26, provided that the fix only affects threads other than the main one. Thanks.
