+Summary: implicit operator on structs issue
+
+The following C# program should print 1 but prints 0 instead.
+Strangely enough moving 
+static private LayerMask mask = 1; makes the problem disappear.
+
+
+
+using System;
+using System.Runtime.CompilerServices;
+using System.Runtime.InteropServices;
+
+[StructLayout (LayoutKind.Sequential)]
+public struct LayerMask
+{
+	private ushort m_Mask;
+	public static implicit operator int (LayerMask mask) { return (int)mask.m_Mask; }
+	public static implicit operator LayerMask (int intVal) { LayerMask mask; mask.m_Mask = 
+unchecked ((ushort)intVal); return mask; }
+}
+
+class Test
+{
+	static private LayerMask mask = 1;
+
+	static void Main ()
+	{
+		int value = mask;
+		System.Console.WriteLine("Output {0}", value);
+	}
+}
