            Bug ID: 15464
           Summary: -Wunused-member-function should probably not fire in
                    this code
           Product: clang
           Version: unspecified
          Hardware: PC
                OS: Linux
            Status: NEW
          Severity: enhancement
          Priority: P
         Component: C++11
          Assignee: unassignedclangbugs at nondot.org

    Classification: Unclassified

We warn at

typedef struct {
  int foo() { return 0; }
} *A;

but such code can be put in a header file (the inline function is not emitted)
and foo can still be used from a .cpp file that includes the header:

typedef struct {
  int foo() { return 0; }
} *A;

extern "C" void f(A x) {
  x->foo();
}
