It's almost certainly going to be easier to rewrite it as something less 
clever, but hey, where's the fun in that?

Any chance of posting some code?

I finally gave up on getting memory management right the first (second, 
nth...) time and started populating my code with debug statements to the 
effect of:

__FILE__::__LINE__ is now creating a __WHATEVER__, address 0xabcddcab
__FILE__::__LINE__ is now deleting a __WHATEVER__, address 0xabcddcab

This made me look like a rank amateur, but also a rank amateur who generally 
was able to leave at 5pm.

You can also try zeroing out the object's memory during destruction -- that 
might let you segfault a bit sooner at a more useful location.  

Combine the two and you should see an object getting freed that is later 
referenced.  

Good luck!
