Random error in Opengl for some reason in my include ssstream i am getting this error when i run: Unhandled exception at 0x005BA1BD

-1

I believe this is some kind of random error thing I am getting only when I run it. I am including my shader files and main in the code below. I am getting a strange error in my include sstream and this it:Unhandled exception at 0x005BA1BD in jippy.cpp.exe: 0xC0000005: Access violation reading location 0xCCCCCCD0. occurred.

struct Shaderprogramsource {

  std::string VertexSouce;

  std::ifstream stream(filepath);

  enum class Shadertype {

      NONE = -1, VERTEX = 0, FRAGMENT = 1
  };

  std::string line;
  std::stringstream ss[2];

  Shadertype type = Shadertype::NONE;

  while (getline(stream, line)) {

      if (line.find("#shader") != std::string::npos) {

          if (line.find("vertex") != std::string::npos)
              type = Shadertype::VERTEX;

          else if (line.find("fragment") != std::string::npos)
              type = Shadertype::FRAGMENT;

      }
      else {

          ss[(int)type] << line << "\n";
      }
  }

  return { ss[0].str(), ss[1].str() };
