System.InvalidOperationException: Unexpected value 'Dup' of type 'Microsoft.CodeAnalysis.CSharp.BoundKind' #1170

Open OwnageIsMagic opened 2 years ago

OwnageIsMagic commented 2 years ago

Looks like bug Roslyn, but it compiles locally. (.NET 6 SDK) Maybe something with Analyzers (it should emit warning CS0168: The variable 'oce' is declared but never used).

using System;
using System.Threading.Tasks;

[assembly: SharpLab.Runtime.NoILRewriting]

// bool catchEx = true;

try { await default(ValueTask); }
//                                ↓↓↓ delete this name
catch (OperationCanceledException oce) when (
                                             false is var catchEx &&
                                                ( (Func<bool>) (() => {
                                                 // ↓↓↓ or this line
                                                 catchEx.ToString();
                                                 return false; }) )()
                                            )
{ }
//catch (Exception) when (catchEx) { }

Thanks for reporting! I can't currently reproduce this -- might be a temporary bug in some specific Roslyn version?
