+Summary: TypeLoadException is thrown
+
+Description of Problem:
+
+Compile following program with mcs and then run it on Microsoft Runtime.
+
+Note: Mono runtime doesn't throw such exception
+
+
+Steps to reproduce the problem:
+1.
+
+using System;
+using System.Runtime.InteropServices;
+
+[StructLayout(LayoutKind.Explicit)]
+struct foo2 {
+}
+
+class C
+{
+ static void Main ()
+ {
+ foo2 f = new foo2 ();
+ }
+}
+
+Actual Results:
+
+Unhandled Exception: System.TypeLoadException: Could not load type foo2
+from ass
+embly t-0, Version=0.0.0.0, Culture=neutral, PublicKeyToken=null because
+field $
+PRIVATE$ was not given an explicit offset.
+ at C.Main()
+
+
+Expected Results:
+
+No exception
+
+Additional Information:
+
+It is caused by this in class.cs
+
+ //
+ // Structs with no fields need to have at least one byte.
+ // The right thing would be to set the PackingSize in a DefineType
+ // but there are no functions that allow interfaces *and* the size to
+ // be specified.
+ //
+
+ if ((Kind == Kind.Struct) && !have_nonstatic_fields){
+ TypeBuilder.DefineField ("$PRIVATE$", TypeManager.byte_type,
+ FieldAttributes.Private);
+ }
