我试图在VSCode中运行一个简单的Hello World程序,但它因分段错误而崩溃。下面是代码:

#include <iostream>

int main() {
  std::cout << "Hello, World!" << std::endl; 
  return 0;
}

当我单击Run C/C++ File时,我在Windows Console中得到以下输出:

Thread 1 hit Breakpoint 1, 0x00007ff7cf5b145d in main ()
Loaded 'C:\WINDOWS\SYSTEM32\ntdll.dll'. Symbols loaded.
Loaded 'C:\WINDOWS\System32\kernel32.dll'. Symbols loaded.

Thread 1 received signal SIGSEGV, Segmentation fault.
0x00007fff49f3c226 in ?? () from C:\Programs\Git\mingw64\bin\libstdc++-6.dll

我已经尝试过更新VSCode和C扩展,重新启动,检查启动配置等解决方案,但到目前为止还没有解决这个问题。
有人能帮助我理解和修复这个segfault时,运行一个简单的C
程序在VSCode?

**编辑:**看起来调试器试图从C:\Programs\Git\mingw64\bin\加载符号。我不确定为什么调试器从这个路径加载符号。我没有在JSON配置中包含它。
**编辑:**实际上,这个问题发生在我做OpenGL任务的时候。一个简单的cout导致整个程序在正常运行之前就崩溃了。我已经尝试在这里包含一个最小可重现的例子。

以下是.vscode文件夹中的JSON配置:

看起来我终于解决了这个问题。我把C:\Programs\Git\mingw64重命名为C:\Programs\Git\mingw64ABC,然后编译我的程序,它运行得很好。然后我把mingw64ABC恢复到它原来的名字,现在一切都正常工作,正如预期的那样。我不确定Windows是否在内部某处缓存了符号搜索路径,这可能是罪魁祸首。我推测一旦操作系统有缓存缺失,它从列表中删除了该路径,并添加了正确的搜索路径C:/msys64/mingw64/bin/
