c++ - 函数调用期间未正确保存 ESP 的值

Question

我正在开发一个 Visual Studio 项目 项目 A(编译时生成静态库)

有一个类(class)

using namespace mynamespace;
class projectAclass
{
  virtual int  funct1()=0;  //Pure virtual function
  virtual int funct2()=0;  //Pure virtual function
  virtual int funct3()=0;  //Pure virtual function
};

项目B(编译时生成DLL)

#define projectBclass_DLL __declspec( dllexport )
class projectBclass_DLL projectBclass: public mynamespace::projectAclass
{
  //Definitions of the 3 pure virtual functions are here
  int funct1() 
  {
    //definition go here
  }
  //similarly for funct2 and funct3

  int funct4()
 { //Definition goes here    }
  int funct5()
 { //Definition goes here    }
  int funct6()
 { //Definition goes here    }
};

现在，从其他项目中创建的主函数中，我创建了一个 projectAclass 类的对象，并尝试调用函数 funct1 但我不知道其他一些函数当我尝试调试解决方案并且从 funct4 返回后，我收到此错误

Run-Time Check Failure #0 - The value of ESP was not properly saved across a
function call.  This is usually a result of calling a function declared with
one calling convention with a function pointer declared with a different calling
convention.

有时您有 calling conventions错误的。有时重建一切就能解决问题。
