I haven't been following this thread, but just debugging a malloc/nand "corruption" issue myself.  I'm going to start a new thread on the subject since its more related to malloc.  However can you try the following and see what happens:

diff --git a/include/malloc.h b/include/malloc.h
index 3e145ad..19f0f0b 100644
--- a/include/malloc.h
