+Summary: unknown operator: long_conv_to_ovf_u1_un
+
+Description of Problem:
+We seems to have incomplete checked support in the JIT.
+
+
+Steps to reproduce the problem:
+1. Compile the following source code
+
+class T {
+	static void Main (string[] args) 
+	{
+		ulong ul = System.UInt64.Parse (args[0]);
+		byte b = checked ((byte) ul);
+		System.Console.WriteLine (b);
+	}
+}
+
+2. Execute it with 249 as it's parameter
+
+3. Execute it with 256 as it's parameter
+
+
+Actual Results:
+mono chk.exe 249
+
+** ERROR **: unknown operator: long_conv_to_ovf_u1_un
+aborting...
+Aborted
+
+mono chk.exe 256
+
+** ERROR **: unknown operator: long_conv_to_ovf_u1_un
+aborting...
+Aborted
+
+
+Expected Results (ms runtime):
+chk 249
+249
+
+chk 256
+Unhandled Exception: System.OverflowException: ...
+
+
+How often does this happen? 
+Always
+
+
+Additional Information:
+Even without parameters we receive the same abort with Mono.
+
+mono chk.exe
+
+** ERROR **: unknown operator: long_conv_to_ovf_u1_un
+aborting...
+Aborted
