Description Carlos O'Ryan 2004-09-20 18:03:57 CDT 
This refers to the helper class returned by operator[] in sequences of strings,
wide-strings and object references.  This helper class is required to have an
assignment operator that releases the  underlying element *only* if the sequence
release flag is true.

TAO's implementation honors this requirement, but it also increments the
reference on the rvalue assigned to the sequence element.  Regardless on the
release flag value.

If the release flag is false the application is in charge of releasing this
memory, but I do not think the application should be expected to release some
elements that the sequence decided to duplicate on its own.  The spec is silent
but I believe the approach described in this bug report follows the principle of
least surprise.
