+Summary: Possible conversion bug associated with Int64.
+
+Please fill in this template when reporting a bug, unless you know what you
+are doing.
+Description of Problem:
+ 
+        Apparently either Int64 or ToInt64 aren't correctly raising the
+OverflowException.
+ 
+Steps to reproduce the problem:
+1.
+ 
+        Compile the source code included at the end of this message.
+  
+2.
+ 
+        Run the resulting executable.
+ 
+3.
+ 
+        Observe how the second conversion overflowed without raising the
+correspondant exeption.
+ 
+Actual Results:
+ 
+        The second conversion is wrong.
+ 
+Expected Results:
+ 
+        The second conversion would have shown a sequence of nines (and
+nines only).
+ 
+How often does this happen?
+ 
+        Every time.
+
