+Bug#: 81815
+Product: Mono: Compilers
+Version: unspecified
+OS Details: Debian Lenny
+Status: NEW   
+Priority: Normal
+Component: C#
+AssignedTo: rharinath at novell.com                            
+ReportedBy: bzximian.3.crazycomputers at neverbox.com               
+QAContact: mono-bugs at ximian.com
+TargetMilestone: ---
+Summary: mcs allows covariance from reference to value types
+Steps to reproduce the problem:
+1. Compile the testcase.
+2. ???
+3. Profit.
+Actual Results:
+Compilation succeeds and the program blows up when run, presumably because
+the int returned from int.Parse was stored as an address to a managed object.
+Expected Results:
+MS csc gives CS0407.  mcs should probably do something similar.
+Additional Information:
+The binary produces the same result when run on the MS runtime.  Unless the
+location is not trusted, and then a VerificationException is thrown.
