I ran the attached QV file and it ran well: no memory leaks.
However, I then published the Movie Path connector and ran leaks
again. This output is attached.
you would need to give more details: are you observing the leak in
your custom application only, or can you reproduce it in the Quartz
Composer editor?
I also tried out the leaks technique on my original composition
when it was being executed as an application rather than through
Quartz Composer, and found that there were some leaks here too.
Both traces are attached.
Those traces do not really show leaks in Quartz Composer.
