@narimiran This seems to be only on macOS ARM and only in CPP mode and only with Nim ≥ 2.0. Changing platforms or using C or using Nim 1.6 does not have the problem.

[narimiran]

Yes.
My logic was: if we're not testing both ORC and refc, then I thought it should be consistent and use just refc for all Nim versions.
