Comment(by steven_watanabe):

 I'm afraid I don't understand why this should be considered a GCC bug.

 3.4.2 says:

 If T is a template-id, its associated namespaces and classes are the
 namespace in which the template is defined; for member templates, the
 member template’s class; '''the namespaces and classes associated with the
 types of the template arguments provided for template type parameters'''
 (excluding template template parameters); the namespaces in which any
 template template arguments are defined; and the classes in which any
 member templates used as template template arguments are defined. [Note:
 nontype template arguments do not contribute to the set of associated
 namespaces. ]

 (emphasis added)
