Bug ID: 25258
Summary: -Wnon-virtual-dtor should not trigger if the base
class has a protected destructor
Product: clang
Version: trunk
Hardware: PC
OS: Linux
Status: NEW
Severity: normal
Priority: P
Component: C++
Assignee: [email protected]
Reporter: [email protected]
CC: [email protected], [email protected]
Classification: Unclassified
struct A { virtual void a(); protected: ~A() = default; };
struct B : public A { void a() override; };
/tmp/t.cc:2:8: warning: 'B' has virtual functions but non-virtual destructor
[-Wnon-virtual-dtor]
struct B : public A { void a() override; };
^
1 warning generated.
As there is no way to destruct a B object through an A pointer, this should be
allowed.
