+Summary: Error CS0136 for compiling program -- scope issue
+
+Description of Problem:
+
+Scopes seem to work differently in Java and C# per mcs and javac -- not
+sure if this is the case:
+
+Compiling C# program with 0.26 mcs gives:
+
+class Scope
+{
+    bool condition;
+
+    Scope()
+    {
+        condition = true;
+
+        if ( condition )
+        {
+            int inner = 0;
+            Console.WriteLine( " .. inside if block .. " );
+        }
+
+        int inner = 0;
+        Console.WriteLine( " .. top level scope .. " );
+    }
+
+    public static void Main()
+    {
+        Scope test = new Scope();
+        Console.WriteLine( " .. fini scope test .. " );
+    }
+}
+
+gives the following error message:
+
+Scope.cs(15) error CS0136: A local variable named `inner' cannot be
+declared in this scope since it would give a different meaning to `inner',
+which is already used in a `child' scope to denote something else
+Compilation failed: 1 error(s), 0 warnings
+
+Expected Results:
+Additional Information:
+
+The corresponding Java program compiles and runs:
+class Scope
+{
+    boolean condition;
+
+    Scope()
+    {
+        condition = true;
+
+        if ( condition )
+        {
+            int inner = 0;
+            System.out.println( " .. inside if block .. " );
+        }
+
+        int inner = 0;
+        System.out.println( " .. top level scope .. " );
+    }
+
+    public static void main( String[] args )
+    {
+        Scope test = new Scope();
+        System.out.println( " .. fini scope test .. " );
+    }
+}
+~/j2sdk142/bin/java Scope
+ .. inside if block .. 
+ .. top level scope .. 
+ .. fini scope test .. 
+
+I thought scopes would work similarly in this case:
