[alert] 65#65: worker process 74 exited on signal 11 (core dumped)

使用lua-nginx-module-0.10.29编译到Nginx后，会不定时出现异常
[alert] 65#65: worker process 74 exited on signal 11 (core dumped)
退回到lua-nginx-module-0.10.28后一直稳定，不会异常退出

经过来回切换版本（仅切换了lua-nginx-module)观察的结果

would you please provide a reproduciable test case？

[bobyang007]

lua-nginx-modules 0.10.29
发现，只要使用了ngx.timer.at，就会引起进程异常

I can't reproduce the crash with the above config.
