我正在 C++ 中实现状态模式，通常一切正常并且根据需要工作，但是在状态多次更改后我出现分段错误，堆栈分配不断上升直到达到最大值，然后崩溃雇用代码： 接口：

class ControllerT1; // Forward declaration

class IControllerStateT1 {
public:
    virtual ~IControllerStateT1() {}
    virtual void handle(ControllerT1* controller) = 0;
};



class ControllerT1 {
    public:
        ControllerT1(std::vector<int> &input, std::vector<int> &output);
        ~ControllerT1();

        void stop();
        void initialize();
        void run();

        void setState(IControllerStateT1* newState);

    private:
        IControllerStateT1* currentState;
};


#include "ControllerT1.h"
#include "StopT1.h"

ControllerT1::ControllerT1(std::vector<int> &input, std::vector<int> &output) : currentState(new StopT1()) {
//  ControllerInputs = input;
//  ControllerOutputs = output;
}

ControllerT1::~ControllerT1() {
    delete currentState;
}

void ControllerT1::run() {
    currentState->handle(this);
}

void ControllerT1::stop() {
    currentState->handle(this); …
