Description of Problem:
My app crashes after I have inserted ca. 9000-10000 entries into a
System.Collections.Generic.Dictionary<IntPtr, WeakReference>. In between there
are also some removals.

Steps to reproduce the problem:
I wasn't able to produce a test case.. Up to now I can only reproduce it with
this app.


Actual Results:
UNHANDLED EXCEPTION: System.Reflection.TargetInvocationException: Exception 
has been thrown by the target of an invocation. ---> 
System.IndexOutOfRangeException: Array index is out of range.

Expected Results:
No crash.

How often does this happen? 
Always after some thousands of insertions. It's not fixed to a specific number,
though. It's always between 8000 and 10000.

Additional Information:
A Hashtable works well and doesn't crash.
