--- Comment #10 from peien luo <coollpe at hotmail dot com> ---
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)
