为什么我所有的 C++ 程序都以 0xc0000139 退出?
我正在尝试自学使用 C++ 编程，并在安装了 g++ 的 Windows 上使用 Cygwin.在我开始声明字符串变量之前，一切都很顺利.将字符串文字与 cout 一起使用不会导致任何问题，但是一旦我声明了字符串变量，程序将不再运行.
I am trying to teach myself to program in C++ and am using Cygwin on Windows with g++ installed. Everything was going swimmingly until I started to declare string variables. Using string literals with cout causes no issues, but as soon as I declare a string variable the program will no longer run.
#include <iostream>
#include <string>
int main ()
{
std::string mystring = "Test";
std::cout << mystring;
return 0;
}
前面的代码编译没有问题，但是运行时没有输出.GDB 为我提供了以下内容:
The preceding code compiles without issue, but when run produces no output. GDB provides me with the following:
(gdb) run
Starting program: /cygdrive/c/Projects/CPP Test/string.exe
[New Thread 8416.0x2548]
[New Thread 8416.0x2510]

[Thread 8416.0x14f4 exited with code 3221225785]
During startup program exited with code 0xc0000139.
据我所知，这是 DLL 的某种入口点问题，但我可能完全错了.
From what I have managed to gather this is some sort of entry point issue with a DLL, but I could be completely wrong.
有谁知道我做错了什么或配置错误以及如何解决?
Does anyone know what I have done wrong or what I have misconfigured and how to fix it?
推荐答案
好吧，我不确定到底是什么问题(如果有人知道，我将不胜感激！)，但我能够自己解决它从 GCC 5.2.0 降级到 GCC 4.9.3.
Well I'm not sure what the problem was exactly (if anyone knows I'd be grateful!), but I was able to solve it for myself by downgrading from GCC 5.2.0 to GCC 4.9.3.
