Just FYI,
It's so weird, I have to work around it first.
1, I don't think there's any wrong with the code.
2, I cannot reproduce this issue on my machine, but Huilong can reproduce it on different machines. As Adrien said, it may be a compile issue. I guess it's a compiler issue. Maybe gcc 4.8.5 has its own problem. (I'm using gcc 4.8.3 which is fine.)
