+Summary: [GMCS] InvalidCastException when copying Dictionary
+
+Description of Problem:
+
+The following sample:
+
+using System.Collections.Generic;
+
+class M {
+  public static void Main ()
+  {
+    Dictionary<int,string> d = new Dictionary<int,string>();
+        d[10] = "foo";
+        Dictionary<int,string> copy = new Dictionary<int,string>(d);
+  }
+}
+
+throws an exception during runtime:
+
+Unhandled Exception: System.InvalidCastException: Cannot cast from source
+type to destination type.
+in <0x000af>
+System.Collections.Generic.Dictionary`2[System.Int32,System.String]:.ctor
+(IDictionary`2 , IEqualityComparer`1 )
+in <0x0001f>
+System.Collections.Generic.Dictionary`2[System.Int32,System.String]:.ctor
+(IDictionary`2 )
+in <0x00061> M:Main ()
+
+However there are no castclass opcodes in the corresponding IL, so I guess
+this is runtime issue.
+
+Additional Information:
+
+I'm using mono SVN/trunk.
