hmmm, well, in any case, I doubt your app is GC.  In VTK5 there is "VTK_REQUIRED_OBJCXX_FLAGS" which was set to build as both GC and MRR.  Now that string is gone in VTK master.  No doubt there is some fancy git thing that can tell us when/where/who/why it was removed?

So I've done a review of the memory management and think I should just bite the bullet and refactor it to both fix your leaks and support ARC.

Cheers,
