Apologies for yet another edit: next time I'll make sure to have the
fully-written report before submitting.

The issue appears to be that GCC will permit a derived class access to a
private static variable of its base class.

Please use this repro example instead https://godbolt.org/g/A3zCLk, because it
has a listing of different test cases.
