+    - Fixed the segmentation fault when reading attributes with multiple threads
+
+      It was reported that the reading of attributes with variable length string
+      datatype will crash with segmentation fault particularly when the number of 
+      threads is high (>16 threads).  The problem was due to the file pointer that
+      was set in the variable length string datatype for the attribute.  That file
+      pointer was already closed when the attribute was accessed.
+
+      The problem was fixed by setting the file pointer to the current opened file pointer
+      when the attribute was accessed.  Similar patch up was done before when reading
+      dataset with variable length string datatype.
