It's a centOS7, kernel has been updated to 3.10.0-327.36.3.el7.x86_64, the
problem still occurs. Some new findings:

1, With gcc 4.8.5, it runs fine for this specific case.
2, With gcc 4.9.4, it stucks at some point, the ps says:
$ ps -flp 13600
F S UID         PID   PPID  C PRI  NI ADDR SZ WCHAN  STIME TTY          TIME
CMD
0 D god       13600  13597 89  80   0 - 26038299885 exit 23:15 pts/9 00:15:28
./test_metaserver
3, With gdb, it runs OK by 'set disable-randomization off' it runs ok as well.
(I need to check it again)
