swift Compiler crash with "Assertion failed: signature || !origType->hasTypeParameter()"

Compiler crash with "Assertion failed: signature || !origType->hasTypeParameter()"

Description

I get this crash building an internal app with a locally built toolchain on Windows from swift/main sync'd 5 days ago. I thought this is https://github.com/apple/swift/issues/73198 but its fix https://github.com/apple/swift/pull/73215 doesn't fix it. So splitting that into an new issue here.

Reproduction

None yet. It's from an internal app build.

Stack dump

error: compile command failed due to exception 3 (use -v to see invocation)
Assertion failed: signature || !origType->hasTypeParameter(), file S:\SourceCache\swift\include\swift/SIL/AbstractionPattern.h, line 529
Please submit a bug report (https://swift.org/contributing/#reporting-bugs) and include the crash backtrace.

I bisected this issue to https://github.com/apple/swift/commit/3e637b0afb9db1158e3c0e1fe9b6434893a929a5 which is https://github.com/apple/swift/pull/73129.

If I rebuild the toolchain at that commit, this crash happens and at the previous commit https://github.com/apple/swift/commit/7ef1701f6f7e60d34953b8794e77bab35bac3d77, it does not.

This is still broken at head and our internal Windows toolchain release is blocked.

@slavapestov Do you have any thoughts?

I was able to reproduce the crash on macOS with a program that's is publicly-accessible:

          mainQueue.schedule(after: .init(mainQueue.now.dispatchTime)) { }
      }
}

Two corrections/clarifications

The above self-contained reproducer in https://github.com/apple/swift/issues/73345#issuecomment-2105325350 needed a correction for it to compile successfully when it doesn't crash: the second schedule method's action parameter needed fatalError() in its body. Updated in place.
For the compiler to build successfully at commit https://github.com/apple/swift/commit/3e637b0afb9db1158e3c0e1fe9b6434893a929a5 or the previous commit https://github.com/apple/swift/commit/7ef1701f6f7e60d34953b8794e77bab35bac3d77, the swift-syntax repo needs to be at commit https://github.com/apple/swift-syntax/commit/39b4c4108375ad242a4e48d49e8ddcc837b7d52c

CC @slavapestov thanks for looking into this

Here is an even smaller reproducer

actor GenericActor<K> {
  var i: Int = 0
  private func outerFunc() {
    func accessSelf() -> Int {
      return 0
    }
    print(accessSelf())
  }
}

This seems to be an issue when the isolation parameter is of generic type. https://github.com/apple/swift/pull/73830 appears to fix the issue.
