c++ - ostringstream 对象创建导致我的程序崩溃

Question

我的程序在创建 ostringstream 类的对象时总是崩溃。我无法理解导致它崩溃的原因？

程序:

#include <string>
#include <sstream>
#include <iostream>

DDF foo::send(const DDF& in)
{

    ostringstream os;  <-- causing crash always
    os << in;
    string ostr(os.str());
  ..
}

尝试获得更好的编译器，例如 GCC 4.8.2(或更高版本)或 clang(最新为 3.5)。
