以下代码使用GCC 4.9.2成功编译，没有任何警告：
#include <memory>
#include <string>
#include <boost/regex.hpp>
int main()
{
boost::wregex wregex;
std::wstring text = L"foobar";
return boost::regex_match(text, wregex);
}
命令运行是：
g++ -I /opt/boost/x86_64/1.60.0/include -L /opt/boost/x86_64/1.60.0/lib test.cc -lboost_regex
但与GCC 5.2.0一起使用时显示以下错误：
