--- Comment #10 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
Reduced slightly more:

namespace boost {}
template <typename> struct C { };
template <typename Skipper>
struct StructDecoder : C<Skipper>
{
  StructDecoder()  {
    namespace bs = boost;
    using namespace bs;
  }
};
void NFGParserparse() {
  StructDecoder<int> q_syslog_desc;
}

Still ICEs on the trunk
