In this repo, with clj installed run:
rm -r out; rm -r ~/.cljs/; clj -Srepro --main cljs.main --compile hello.core --repl-options "{:launch-browser false}" --repl
Which logs these warnings:

I am most interested in the last one.
Line 1193 it is referencing in the warning is this line in the test.check repo: https://github.com/clojure/test.check/blob/104fec0c53dcf90c8ce30f4efce67d041b175326/src/main/clojure/clojure/test/check/generators.cljc#L1193
