+Summary: GCHandle.AddrOfPinnedObject gives incorrect address for arrays
+
+Description of Problem: 
+ 
+When a GCHandle with GCHandleType.Pinned is created, it should be possible 
+to obtain the address of the object with GCHandle.AddrOfPinnedObject(). 
+When the object in question is an array, Mono appears to return a pointer 
+to some header information that preceeds the actual appear data. However, 
+Rotor returns a pointer to the first element of the array. See the 
+"Results" section below. 
+ 
+Steps to reproduce the problem: 
+1. gcc -shared -o libtest.so test.c 
+2. mcs test.cs 
+3. mono test.exe 
+ 
+Actual Results: 
+ 
+135270400 135270400 
+size of array[x]: 1 
+==> array(0) = 168 
+==> array(1) = 208 
+==> array(2) = 4 
+==> array(3) = 8 
+==> array(13) = 48 
+==> array(1998) = 1 
+==> array(1999) = 2 
+ 
+Expected Results: 
+ 
+1093363496 1093363496 
+size of array[x]: 1 
+==> array(1982) = 1 
+==> array(1983) = 2 
+ 
+ 
+How often does this happen?  
+ 
+Always
