this small program:
class Resource
{
public:
int* data{};
void work();
Resource(){};
// User-declared destructor triggers the warning under -Wdeprecated-copy
~Resource() {
delete data;
}
// No user-declared Copy Constructor or Copy Assignment Operator
// Clang implicitly generates these, which is deprecated here.
};
void create_copy() {
Resource r1;
// Warning: Call to implicitly-deleted copy constructor
Resource r2 = r1;
r2.work();
}
using: -std=c++11 -v
if I remove:
r2.work();
it compile
here is the error and the stack dump from godbolt.org
