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。我无法理解是什么导致它崩溃？

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，如GCC 4.8.2（或更高版本）或clang（最新版本为3.5）。
