            Bug ID: 43329
           Summary: -Wshadow-field triggered in static member functions
           Product: clang
           Version: unspecified
          Hardware: All
                OS: All
            Status: NEW
          Severity: normal

-Wshadow-field is triggered in static member functions for inherited,
non-static data members. Is this actually helpful? Since static member
functions don't have access to a this pointer anyway (and no implicit access to
its data members when "this->" is omitted), there can be no ambiguity.

See https://wandbox.org/permlink/Fsdh6hvPhoCurwo5

class C {
    int x;

class D : public C {
    static int f (int x) { return x; }

int main() {}

Results in warning: parameter 'x' shadows member inherited from type 'C'
