It's become a libstdc++ test, but anyway:  -O -fstrict-aliasing

   typedef int Context_t;
   namespace Arch {

   inline Context_t context() {
  }
   inline int contexts() {

  };

template<int Dim> class Grid;
template<class DT> class DomainBase {
  };
template<int Dim, class DT> class Domain : public DomainBase<DT> {
  };
#include <vector>
template<> class Grid<1> : public Domain<1, DomainTraits<Grid<1> > > {

    PatchSizeSyncer(int contextKey, Grid_t &localGrid);
    int myContext_m;
    int numContexts_m;
    int localKey_m;
    Grid_t localGrid_m;
    typedef std::pair<int,Grid_t *> Elem_t;

 }

myContext_m(Pooma::context()),     numContexts_m(Pooma::contexts()),    
localKey_m(contextKey),     localGrid_m(localGrid) {
    if (myContext_m == 0) gridList_m.reserve(numContexts_m);
  }
 }
