+Summary: BitArray.And should modify object
+
+Description of Problem:
+When the And-method is called on an instance of the class BitArray in 
+System.Collections, e.g. "a.And(b)", the instance "a" should be modified. 
+Now a new object is created and returned and the instance, a, is left 
+unmodified.
+
+Steps to reproduce the problem:
+1. Paste the C# code-example into a file called "test.cs" from
+http://msdn.microsoft.com/library/en-
+us/cpref/html/frlrfsystemcollectionsbitarrayclasstopic.asp
+2. compile it
+
+Actual Results:
+
+  Using Monos implementation:
+  (note the line marked with "****")
+
+  H:\test>mono test.exe
+  Initial values
+  myBA1:  False   False   True    True
+  myBA2:  False   True    False   True
+
+  Result
+  AND:    False   False   False   True
+
+  After AND
+  myBA1:  False   False   True    True ****
+  myBA2:  False   True    False   True
+
+  Exception: System.ArgumentException: An invalid argument was specified.
+  in <0x00080> 00 System.Collections.BitArray:And 
+(System.Collections.BitArray)
+  in <0x0031d> 00 .SamplesBitArray:Main ()
+
+Expected Results:
+
+  Using Microsofts implementation:
+  (note the line marked with "****")
+
+  H:\test>test.exe
+  Initial values
+  myBA1:  False   False   True    True
+  myBA2:  False   True    False   True
+
+  Result
+  AND:    False   False   False   True
+
+  After AND
+  myBA1:  False   False   False   True ****
+  myBA2:  False   True    False   True
+
+  Exception: System.ArgumentException: Array lengths must be the same.
+     at System.Collections.BitArray.And(BitArray value)
+     at SamplesBitArray.Main()
+
+How often does this happen? 
+Always
+
+Additional Information:
+Using the binary version of mono version 0.24.
