Type Bug
Environment

First noticed in the GH Actions environment, but it also reproduces using the Swift in `helje5/arm64v8-swift-dev:5.5.1` (and presumably any Linux environment w/ Swift 5.5).

relates to:

  • SR-15532 Compiler doesn't load public property declarations in another module under some conditions.

Issue Description:

I have a small package called `xsys` which wraps and re-exports Glibc/Darwin:

https://github.com/NozeIO/xsys

This works fine on Darwin in general, but starts to break when compiling the tests on Swift 5.5 (tried both, 5.5.0 and 5.5.1):

https://github.com/NozeIO/xsys/runs/4141154588?check_suite_focus=true

The extension is defined here:

https://github.com/NozeIO/xsys/blob/084e2ff0667dd43f0a31868aa40463b287d2d9df/Sources/xsys/timeval_any.swift#L76

E.g.:
```swift
extension timeval : timeval_any {

@inlinable
public static var now : timeval {
var now = timeval()
_ = gettimeofday(&now, nil)
return now
}
```

When compiling the tests, Swift doesn't see that anymore. I tried removing the protocol conformance, removing the inline, neither helps.

Seems to be fixed with Swift 5.8.1:
