Issue Description:

The attached project crashes the compiler with Segmentation fault: 11, if built on RELEASE configuration (works as expected on DEBUG). Even the Xcode editor breaks (shows the yellow question mark).

The example contains a SwiftUI View that tries to use an extension defined in another target, if the extension contains a public ViewModifier it crashes, if it is private/internal, it does not. It also crashes if the extensions only returns self, or some other simple thing, like using .disabled.

There are some variations on what crashes or not commented in the project, originally I detected it in a much bigger iOS project, but was able to reduce to this macOS Package.
