Bug ID: 86652
Summary: pointer to function type cannot have 'const' qualifier
Product: gcc
Version: 9.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: zhonghao at pku dot org.cn
Target Milestone: ---
The code is as follow:
class C {
public:
template <typename i>
int (*f())() const;
};
g++ accepts the code, but clang++ rejects it:
code4.cpp:4:7: error: pointer to function type cannot have 'const' qualifier
int (*f())() const;
^
1 error generated.
If it's a pointer to a const function, the line shall be:
int (*f() const)();
If the return type is const (which is of course meaningless), the line shall
be:
const int (*f())();
However, I do not quite understant int (*f())() const;. Maybe it is illegal as
clang++ says?
