           Summary: misused Type.GetInterfaceMap() causes runtime crash
    Classification: Mono
           Product: Mono: Runtime
           Version: SVN
          Platform: i686
        OS/Version: Windows Vista
            Status: NEW
          Severity: Minor
          Priority: P5 - None
         Component: misc
        AssignedTo: mono-bugs at lists.ximian.com

Type.GetInterfaceMap(), when used for interface type (as the calling object),
should raise ArgumentException. Mono just causes runtime crash without throwing
AE.

using System;
using System.Collections.Generic;
using System.Collections.ObjectModel;
using System.Reflection;

public class Test
{
        public static void Main ()
        {
                typeof (IList<int>).GetInterfaceMap (typeof
(ICollection<int>));
        }
}


Reproducible: Always

Actual Results:  
$ mono ./iface.exe
Stacktrace:

  at (wrapper managed-to-native) System.Type.GetInterfaceMapData
(System.Type,System.Type,System.Reflection.MethodInfo[]&,System.Reflection.MethodInfo[]&)
<0x00004>

  at TESt.Main () <0x00025>

Expected Results:  
ArgumentException ("This" cannot be an interface type).
