Bug ID: 91407
Summary: Wnon-virtual-dtor should't fire for classes with
operator delete=delete
Product: gcc
Version: 8.3.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: asorenji at gmail dot com
Target Milestone: ---
Okay, attempt of delete polymorphic class without virtual destructor, lead to
UB. But, I want trivially destructible class with virtual functions. So, I just
mark operator delete as delete. No delete expression - no problem. But gcc
still show me a warning.
gcc (Debian 8.3.0-6) 8.3.0
Command line:
gcc main.cpp -Wnon-virtual-dtor
Source:
class Test
{
public:
virtual void foo(){}
void operator delete(void*)=delete;
};
int main()
{
return 0;
}
Yes, yes, although "delete pointer" don't work, "::delete pointer" still
worked. But it's just a shoot in the foot.
