    TBD_CTF_FORMAT_OPEN_ISSUES (1) - 
    This testcase makes a note of the case of a probable misrepresentation.
-   See Note 1 and Note 2 below.
+   See Note 1 below.
 
    In the CTF section, these types are encoded as :
 
      Variables:
-      _CTF_NEWSTR ->  7: const char [0] (size 0x0)
-      _CTF_SECTION ->  6: const char [5] (size 0x5)
-      b1 ->  2: int [0] (size 0x0)
-      b2 ->  3: int [0] (size 0x0)
+      b1 ->  3: int [0] (size 0x0)
+      b2 ->  5: int [0] (size 0x0)
 
     Note 1 : There is misrepresentation in that b1 and b2 are specified
     differently by the user.
-    Note 2 : It is arguable though whether the representation for
-    _CTF_NEWSTR is incorrect.  */
+    
+    In this testcase, two CTF array records each of type int [0] is expected.  */
