virtual destructor prevents an object being created on the device

Runtimes OpenMP
#1

I would like to know why a class that has virtual destructor can not be
instantiated on the device while virtual methods are ok.

#2

Below code can’t be built with OpenMP offloading flags enabled:

class Base {
public:
virtual void operator()() = 0;
};

class Derived : Base {
public:
void operator()();
};
int main() {
#pragma omp target parallel for
for (int i =0;i<100;i++) {
Derived d;
}

}

#3

Sorry Alexey, I meant this code:

[kitayama1@juron1-adm pcp0151]$ cat tmp.cpp
class Base {
public:
virtual ~Base() {
}
virtual void operator()() = 0;
};

class Derived : public Base {
public:
virtual void operator()();
};

void Derived::operator()() {
// int x=0;
}
int main() {
#pragma omp target parallel for
for (int i =0;i<100;i++) {
Derived d;
}

}

[kitayama1@juron1-adm pcp0151]$ clang++ -fopenmp -fopenmp-targets=nvptx64 tmp.cpp
