替换此:

class IntegrFunction
{
public:
    Function* function;
};

与此:

class IntegrFunction
{
public:
    Function function;
};

您的typedef已经创建了一个函数指针.声明Function* function会创建一个指向函数的指针.

Your typedef already creates a pointer-to-function. Declaring Function* function creates a pointer-to-pointer-to-function.
