cache-references.c:

  pe.config=PERF_COUNT_HW_CACHE_REFERENCES;
  ...
      for(i=0; i<ARRAYSIZE; i++) {
        array[i]=(double)i;
      }
  ...
  if (!quiet) printf("\tL1 D accesseses: %lld %lf\n",count,aSumm);

PERF_COUNT_HW_CACHE_REFERENCES is counting LLC references on many
platforms. Did you mean to use PERF_COUNT_HW_CACHE_L1D here?
