It only happens in release builds, and only on watchOS.

An alternative repro would be to open the solution "tests/mini/mini-watchos.sln" and run the Release|Device configuration of the "mini-watchos-app" project.

I've tested master, d15-5, d15-4 and d15-3, and it fails everywhere, so if it's a regression, it's not a recent one.
