Difficulty integrating with Swift/Objective-C

line 585 of weak-set.c. 4. I've also sometimes seen this one, https://lists.gnu.org/archive/html/emacs-bug-tracker/2020-01/msg00365.html, although perhaps that's indeed related to closed stdout. Because these errors are different all the time i guess it's some race condition or threading issue?
