DPC++ Compile failed on std::make_shared when apply to class with virtual function

shenuo — Sun, 27 Aug 2023 03:54:51 GMT

#include <CL/sycl.hpp>

#include <iostream>

#include <memory>

class A {

public:

int v = 0;

virtual void func() {};

};

class B : public A {

public:

virtual void func() override {

std::cout << 1 << std::endl;

std::cout << this << std::endl;

std::cout << reinterpret_cast<unsigned int>(this) << std::endl;

}

};

class C : public A {

public:

virtual void func() override {

std::cout << 2 << std::endl;

std::cout << this << std::endl;

std::cout << reinterpret_cast<unsigned int>(this) << std::endl;

}

};

int main()

{

//auto ptr = std::make_shared<B>();

std::shared_ptr<A> ptr = std::make_shared<B>();

std::shared_ptr<A> ptr2 = std::make_shared<C>();

/*auto ptr = std::make_shared<B>();

auto ptr2 = std::make_shared<C>();*/

std::cout << reinterpret_cast<unsigned int>(ptr.get()) << std::endl;

ptr->func();

std::cout << reinterpret_cast<unsigned int>(ptr2.get()) << std::endl;

ptr2->func();

return 0;

}

code above can be compiled by using other c++ compiler,

I use DPC++ 2023 +vs2022

however DPC++2022 +vs2019 is ok

I'm sorry .

code above CAN NOT be compiled by using other c++ compiler, return error: error: 14;

I use DPC++ 2023 +vs2022

however, DPC++2022 +vs2019 is ok

Hi,

Thanks for posting in Intel Communities.

Based on our internal discussion about creating a priority ticket if needed, I am going ahead and closing this case for now.

Please feel free to contact us further if you need any assistance from our side.

Thanks & Regards,
