SDK 3.1.401 fails to compile switch expression #12886

Open Saalin opened 3 years ago

Saalin commented 3 years ago

SDK 3.1.401 fails to compile switch expression, works fine on 3.1.301 and ends with MSB6006 "csc.exe" exited with code -2146232797. on 3.1.401

Minimal working example

public class Program {
  public static void Main() {}

  public static class FooBar {
    public static string For(string a, string b) =>
     (a, b) switch { ("x", ConstClass.FooKey) =>"v1",
      ("x", ConstClass.BarKey) =>"v2",
      ("y", ConstClass.QuxKey) =>"v3",
      (_, ConstClass.QuxKey) =>"v4",
      _ => throw new Exception()
    };
  }

  public class ConstClass {
    public const string FooKey = "FOO";
    public const string BarKey = "BAR";
    public const string QuxKey = "QUX";
  }
}

Got the same error. Tried with 3.1.302 and it works fine.
