Description

The following code snippet results in a SIGSEGV on iOS when building with <MtouchInterpreter>-all</MtouchInterpreter>.

// obj must be 'IInterface<Implementation>', can't repro when declaring as 'Implementation'
IInterface<Implementation> obj = new Implementation();
Func<object, Implementation> action = obj.Method;
Action.Invoke(default!);

public interface IInterface<out TValue>
{
    TValue Method<TInterface>(TInterface parameter) where TInterface : class; // constriant required, any constraint still repros
}

// implementation must be struct
public struct Implementation : IInterface<Implementation>
{
    public Implementation Method<TInterface>(TInterface parameter) where TInterface : class =>
        new Implementation();
}

Reproduction Steps

  1. Create iOS project via templates (dotnet new ios)
  2. Add <MtouchInterpreter>-all</MtouchInterpreter> to the iOS project file
  3. Add the code snippet mentioned in description somewhere in the project.
  4. Build project and run application on a physical device.

Expected behavior

Code runs fine.

Actual behavior

Code fails when the delegate is created, with the following crash report:

Probably the same as
#89076
That issue will be fixed in a future preview release/8.0 final, but the fix didn't make preview7.

@frenzibyte - I'm closing this as fixed with PR #89142. If you find an issue after testing with .NET8 RC1 build, please re-open.
