After debugging the object code, I can see that the error occurs because
of corruption in the internal AVL tree; the bug occurs during an
insertion into the AVL tree in avl_insert(), namely when nullifying
node->avl_child[0]:
node->avl_child[0] = NULL;
node->avl_child[1] = NULL;
>From what I gather, it looks like there is some internal memory
corruption probably causing this issue. Without a full kernel core I
can't track this back much further, so my current hunch is that this may
not be a software error after all. I've had an extensive hunt around
and cannot find similar breakage patterns, so I'm fairly confident this
may be a one-off memory issue. I'm going to close this as Won't Fix,
but if it happens again, please feel free to re-open the bug.
