Not necessarly, as the allocated memory is *still reachable*
(there are pointers to them)

First of all run with GLIBCPP_FORCE_NEW=1 set in the environment.
This will make sure libstdc++ (assuming you're using the GNU version)
won't keep memory allocated on delete.

Second, you implemented something new, so you're likely returning
String values in the environment, so I'd expect more memory to
be used there (more ActionScript variables will have real values rather
then being undefined).

As long as no *suppressed* errors reported you're doing nothing nasty.
