[Bug c++/37970] New: ICE in some (probably mal-formed) template code

["keenan dot forbes at gmail dot com" <gcc-bugzilla at gcc dot gnu dot org>]

This code (for better or worse) appeared to have built with 4.0.1. By adding
the "class" stuff in the template specialization the static member was actually
instantiated. With just <> no instantiation occurred.
