--- Comment #2 from Marek Polacek <mpolacek at gcc dot gnu.org> ---
This should probably be caught in redeclaration_error_message but isn't because

 2991       if (TREE_CODE (DECL_TEMPLATE_RESULT (newdecl)) != FUNCTION_DECL
 2992           || (DECL_TEMPLATE_RESULT (newdecl)
 2993               == DECL_TEMPLATE_RESULT (olddecl)))
 2994         return NULL;

and here DECL_TEMPLATE_RESULT is a VAR_DECL.
