Confusion with watch values during debugging

The debuggee is a mixed (MFC + /clr:OldSyntax) exe. The application is linked with some assemblies (MFC extension DLL's, /clr:OldSyntax enabled)
Compiler settings: Release build, Unicode, Disable optimzation

After a breakpoint is reached, I will watch some values. Here is a look at my watch window:

+ this                      0x01010a8c
+ this->Node                0x00d81718
  this->Node->Name          "Processor"
+ Node                      <undefined vaue>   // Why Node is undefined
- this
   + ObjectBaseData^        0x01010a8c
   - Node                   0x00d81710         // Why the addresses is not 0x00d81718
      - GroupNet^           ....
      + Containers          0x00d81148         // Why the addresses are equal
      + GroupRoot           0x00d81148
      ...
        Name               {...}              // I can't see the name "Processor".o

Hi Jens,

It really looks like you've found a bug in the product. Could you log a bug in the feedback page (http://msdn.microsoft.com/productfeedback). Make sure to put sufficient information to help the team reproduce the problem (sample project is ideal) and we will look at fixing it.

Thanks,
Kris M.
In addition, it might be helpful if you could paste the full output from the watch window, including the types listed to the left.

Thanks,

Hi, Boris!
Here is the watch list with the type column

Thanks for the answer.

No, there isn't the same underlying type.

Is it possible that you are doing some casting of the "Node" element It can often lead to misaligned information.

A couple of things:
First, we have fixed some bugs since Beta 2 that would help for this scenario (pick up June/July CTP if you can to double-check). It might well be that your top complaint won't be addressed though. However, we are continuing to investigate it. Is it possible that this->Node->GroupNet->Containers and this->Node->GroupNet->GroupRoot point to the same underlying address (do they instantiate the same underlying type )

Thanks
