this bug appears when the kernel is built without frame pointer.
a workaround is to enable framepointer in kernel config.
i fixed some bugs in this regard, but i couldn't reproduce this bug
(perhaps related with gcc version, etc).
could you try Jaroslav's bk tree? it includes almost the latest
version:
