异步日志在rollFile的时候导的崩溃

[arhlong]

今天发现产生了coredump，用gdb查看了一下，信息如下：

(gdb) bt
#0 0x0000003af34690e6 in setbuffer () from /lib64/libc.so.6
#1 0x00000000004f6110 in muduo::LogFile::rollFile() () at /home/suyl/project/muduo-1.0.9/muduo/base/LogFile.cc:101

#5 0x0000003af34e8aad in clone () from /lib64/libc.so.6

使用的muduo版本是v1.0.9
