Reduced testcase for this one (-O):

namespace k3d {
    class iunknown {
    };
    class ifile_format :  public virtual iunknown {
    };
    class iapplication_plugin_factory :  public virtual iunknown {
        virtual iunknown* create_plugin() = 0;
    };
    class uuid {
    public:
        uuid(const unsigned long Data1) :   data1(Data1) {
        }
        unsigned long data1;
    };
    template<typename plugin_t> class application_plugin :  public
iapplication_plugin_factory {
        iunknown* create_plugin()  {
            return new plugin_t();
        }
    };
    template<typename context_policy>
    class plugin_factory : public context_policy {
    public:
        plugin_factory(const uuid& ClassID) {}
    };
}
namespace {
    class imagemagick_reader : public k3d::ifile_format {
    public:
        static void get_factory()  {
            static k3d::plugin_factory<
k3d::application_plugin<imagemagick_reader> > factory(    
k3d::uuid(0x4eb70e35));
        }
    };
}
void  imagemagick_reader_factory()   {
     ::imagemagick_reader::get_factory();
}
