One way to narrow this down (though it'll make the kernel dreadfully slow,
why it's a local-tree-only change), would be to walk all the allocations on
both alloc and free and check for red-zone violations. Dumping address and
size (of the allocated offending block) it should be possible to pinpoint
the violator (bug) and terminate its existance.
