Having it public is bad, imo.  But anyways, if you are going to delete
it this you had probably do what TArrayD does internally:

   TArrayD *a = new TArrayD(10);
 
   delete [] a->fArray;
   a->fArray = 0;

Or, looking at the implementation you could replace those last two
lines with:

   a->Adopt(0,0);
