[Bug c++/43282] GCC looks into dependent bases during unqualified lookup

The point is that the scope of the base class is not examined even during
instantiation, so you cannot find the class member function and ADL finds
A::foo instead. The Standard says at 14.6.2/3:

In the definition of a class template or a member of a class template, if a
base class of the class template depends on a template-parameter, the base
class scope is not examined during unqualified name lookup either at the point
of definition of the class template or member *or during an instantiation of
the class template or member*.
