ASAN reports SEGV on unknown address 0x000000000000

Hi @czchen

I added __attribute__((aligned)) to the node struct, however ASAN reports SEGV on unknown address 0x000000000000, do you have idea about that?

No idea, let me study it.

Cannot reprocedure in my machine (Debian/sid, clang-3.7). Let me try to upgrade clang in travis-ci to see if the issue remains.

I have more changed on 2.0 branch, maybe there are some invalid usecase in test cases

This one doesn't use ASAN, but it failed with clang compiled check
