Remove the code in memcache that does a TALLOC_FREE on stored pointers. That's a disaster waiting to happen. If you're storing talloc'ed pointers, you can't know their lifecycle and they should be deleted when their parent context is deleted, so freeing them at some arbitrary point later will be a double-free.
