[Boost-users] Debugging shared_ptr usage

I've got a "leak" with shared_ptr. Basically, I'm pretty sure something is holding onto a reference via shared_ptr I don't want it to. Is there any sort of easy way to track the creation and deletion of shared_ptr's throughout my program to see who is creating shared_ptr's, when they're getting deleted and the reference count being decremented or incremented? Then I can see who is still holding the reference. Thanks, Mike Gibson
