I figured the cache module would be involved in there somewhere. It's really the only thing that does anything major with control attributes...

That's interesting... well I noticed a check was missing for the parenting of VALUE_PAIR data buffers. If one wasn't being copied somewhere in the cache module, and being freed due to incorrect parenting, it'd result in heap corruption.

I've added the check, could you run up v3.0.x HEAD and see if it fails?

I also noticed a missed free when removing cache control attribute, but that'd quite minor, and wouldn't of even resulted in a memory leak...
