+Summary: Uninitialized variable not found by mcs
+
+The attached example taken from  
+"Programming C#" does not produce a compiler errormessage saying that the  
+variable myInt is used uninitialized. It compiles cleanly instead (used  
+mcs v0.11). Furthermore the uninitialized variable was not implicitly  
+initialized to 0 (as good C and C++ compilers do). I don't know, if this  
+is in error as well. The output from the run was 
+ 
+Uninitialized, myInt: -1073746096 
+After assignment, myInt: 5 
+ 
+The code is as follows: 
+ 
+class Values { 
+ 
+    static void Main() { 
+        int myInt; 
+        System.Console.WriteLine("Uninitialized, myInt: {0}", myInt); 
+        myInt = 5; 
+        System.Console.WriteLine("After assignment, myInt: {0}", myInt); 
+    } 
+}
