           Summary: False error: template argument for template type
                    parameter must be a type

           Version: trunk
          Platform: Macintosh

Created an attachment (id=4491)

Source file exhibiting the problem

The attached aap.cxx compiles fine with g++ (and for that matter any other know
compiler), but not with clang++. Do:

clang++ -c aap.cxx
