如何避免 <thread> C++11 中引发的异常？

我正在尝试使用c++ 11中的线程库编写多线程软件。在互联网上找到的一些基本教程可以按预期编译和运行。但是我自己的应用程序总是会抛出一个异常。

谁能告诉我代码的哪一部分应该修复，请?

$ clang++ -std=c++11 -stdlib=libc++ BaseInterface.cxx -c -o BaseInterface.o
$ clang++ -std=c++11 -stdlib=libc++ SocketReceiver.cxx -c -o SocketReceiver.o
$ clang++ -std=c++11 -stdlib=libc++ main.cxx -c -o main.o
$ clang++ -std=c++11 -stdlib=libc++ main.o BaseInterface.o SocketReceiver.o -o main
$ gdb main  
(gdb) run

这是在OS X 10.8上的结果。使用GCC 4.4的Scientific Linux 6也给出了类似的结果。
