            Bug ID: 126860
           Summary: ICE when calling a function pointer data member with a
                    qualified-id from a dependent base class template
           Product: gcc
           Version: 17.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c++
          Assignee: unassigned at gcc dot gnu.org
          Reporter: s.kimura.h41104 at gmail dot com
  Target Milestone: ---

Compiler Explorer: https://godbolt.org/z/96MvTzM94

Reproducer:
```
struct A {
  int (*foo)();
};

template <typename T> struct S : public A {
  void bar() { A::foo(); }
};
```

Backtrace:
<source>: In member function 'void S<T>::bar()':
<source>:6:19: internal compiler error: unexpected expression 'A::foo' of kind
