[corytrese]

This seems to be caused by placing a CCControlButton inside a CCSprite in a CCB scene hierarchy.

I'm detecting the leak with VLD.

[corytrese]

My workaround, until I figure out how to fix in CCReader and contribute ...

Bind the leaky controls in onAssignCCBMemberVariable

CCB_MEMBERVARIABLEASSIGNER_GLUE(this, "ccCharacterImage1", CCControlButton*, this->ccCharacterImage1);

and then add this code in the deconstructor

ccCharacterImage1->removeAllChildren();
ccCharacterImage1->removeFromParent();
CC_SAFE_RELEASE_NULL(ccCharacterImage1);

For me, that fixed it.
