C++11编译运行Segmentation fault.

Hi,升级c++11以后，编译没问题，但是运行初始化client的时候会挂。

gdb如下：

Program terminated with signal 11, Segmentation fault.

348 sofa_client_ = (new sofa::client::SofaClient());
349 sofa_client_->Init(rpc_client_,ip_list_str);

错误出现在347行

请问这是已知错误吗？有解决方案吗？

Start by reproducing the C++11 client initialization failure under gdb and inspect the stack from sofa/pbrpc/rpc_client.cc:16 through sofa/pbrpc/rpc_client_impl.cc:88 and sofa/pbrpc/timer_worker.h:27. Then trace the Boost.Asio service construction at the reported thirdparty/boost/asio files and the caller at XXXCore.cpp:347. Done means identifying the cause and confirming that RpcClient initialization no longer segfaults.
