Bug when testing with Microsoft Composite Application Block

I've isolated a bug when testing with the Microsoft Composite Application Block (CAB) libraries:

http://msdn.microsoft.com/practices/default.aspx?pull=/library/en-us/dnpag2/html/cab.asp

It seems that whenever I instantiate a TestableRootWorkItem while the MockManager is running an exception is incorrectly thrown during the ObjectBuilder phase. This exception is not thrown when TypeMock is not running.

After this I sometimes get the following error when trying to build:

Error 1 A problem occurred while trying to set the "Sources" parameter for the IDE's in-process compiler. Attempted to read or write protected memory. This is often an indication that other memory is corrupt. C:WINDOWSMicrosoft.NETFramework2.0.50727Microsoft.CSHARP.Targets 147 9

The only way to clear the error is to shut down VS2005.

Here is the simple test that shows the failure. (I can provide a zip file with the code if needed):

      [TestMethod]
      public void TestWorkItemFails()
      {
         MockManager.Init();
         
         // The following incorrectly throws an exception
         TestableRootWorkItem mockWorkItem = new TestableRootWorkItem();
         mockWorkItem = null;
         MockManager.Verify();
      }

      [TestMethod]
      public void TestWorkItemSucceeds()
      {
         TestableRootWorkItem mockWorkItem = new TestableRootWorkItem();
         mockWorkItem = null;
      }

Here is the last bits of the TypeMock.out file:
