code snippet
Hello,
I have some code that compile and work fine in gcc 4.6.2 (without tne new
keyword "override" ) but in version 4.7.2 it complie generate access violation
runtime. under windows platform.
So, i need some help, thank you very much:
#include
using namespace std;
struct Entity {
//~Entity() = default; //work fine
~Entity() {} //when i specified my destructor this compile but generate
runtime access viloation
};
template
struct IRepository { virtual T g() = 0; };
struct OtherInterface{ virtual void y() = 0; };
struct IEntityRepository : public virtual IRepository{ };
template
struct RepositoryBase : public virtual IRepository, public OtherInterface{
virtual void y() override { cout << "y() override called" << endl; }
};
template
struct DataRepository : public RepositoryBase{
virtual T f() { cout << "f() called" << endl; this->y(); T t; return t; }
T g() override {
cout << "g() override called" << endl;
when i specified my destructor for class Entity this compile but
generate runtime access viloation here : on this: probably problem with vptr
return this->f(); }
};
struct EffectiveEntityRepository : public DataRepository, public
IEntityRepository{
};
int main() {
IEntityRepository* var = new EffectiveEntityRepository();
var->g();
return 1;
}
