Visual C++读取流到double类型时的异常行为确认请求

以下是测试代码：

#include <iostream>
#include <sstream>
using namespace std;

int main()
{
    istringstream istr("1e-07 3");
    double xx = 0;
    int yy = 0;
    istr >> xx >> yy;
    cout << "xx = " << xx << endl;
    return 0;
}

运行结果随平台工具集和运行时库类型不同存在差异：

Toolset v143, Multi-threaded Debug or Multi-threaded: 1e-06
Toolset V143, Multi-threaded Debug DLL or Multi-threaded DLL: 1e-07
Toolset v142, Multi-threaded Debug or Multi-threaded: 1e-07
Toolset V142, Multi-threaded Debug DLL or Multi-threaded DLL: 1e-07

能否有人确认这一现象？如果这确实是编译器/运行时库的Bug，我会感到非常惊讶。谢谢。
