Bug ID: 23072
Summary: Unjustified warning for D.3
Product: clang
Version: trunk
Hardware: PC
OS: Linux
Status: NEW
Severity: normal
Priority: P
Component: C++14
Assignee: [email protected]
Reporter: [email protected]
CC: [email protected]
Classification: Unclassified
The problem is that an unjustified warning is arisen when explicitly defaulted
copy-constructor is defined when the class has a user-declared copy
assignment operator or a user-declared destructor. $D.3 states it's about
implicit and not explicit definition. Quote:
The implicit definition of a copy constructor as defaulted is deprecated if the
class has a user-declared copy
assignment operator or a user-declared destructor.
Code like this:
struct W {
W(const W&) = default;
int a;
~W() { a = 9; }
};
will emit unjustified warning for now.
