--- Comment #4 from Jonathan Wakely <redi at gcc dot gnu.org> ---
[basic.scope.class] p2:

"A name N used in a class S shall refer to the same declaration in its context
and when re-evaluated in the completed scope of S. No diagnostic is required
for a violation of this rule."

So the code is ill-formed, no diagnostic required.

GCC is allowed to reject it. The other compilers fail to diagnose it (which is
also conforming).
