+Summary: MarshalAs(UnmanagedType.LPStruct) not working
+
+Please fill in this template when reporting a bug, unless you know what you
+are doing.
+Description of Problem:
+MarshalAs(UnmanagedType.LPStruct) does not seem to be working correctly.
+This would be useful for COM Interop
+(http://blogs.msdn.com/adam_nathan/archive/2003/04/23/56635.aspx).
+
+
+Steps to reproduce the problem:
+1. Run attached sample on windows (tries to create IE COM Object).
+2. 
+3. 
+
+Actual Results:
+$ mono lpstruct_test.exe
+Using LPStruct hr = 2147942487          p = 0
+Using ref Guid hr = 0           p = 2437584
+
+Expected Results:
+$ ./lpstruct_test.exe
+Using LPStruct hr = 0           p = 1658764
+Using ref Guid hr = 0           p = 1671772
+
+Note, p is a pointer so values don't need to match. hr should be 0, and p
+should have a non-zero value.
+
+
+How often does this happen? 
+Everytime.
