      #55: memory leaks in AST traversal implementations

 Reporter:  utke             |       Owner:  narayanan
     Type:  defect           |      Status:  new      
 Priority:  major            |   Milestone:           
Component:  OA/Sage to XAIF  |     Version:           
 Keywords:                   |  
-----------------------------+----------------------------------------------
 in the traversal code inherited attributes are returned by value but in
 the ADIC implementation they are locally "new"ed up without being deleted
 anywhere. For example:

 SynthesizedXAIFInfo
     XAIFGlobalTraverse::sageToGraph(SgGlobal *node, InheritedXAIFContext
 inh,
         SynthesizedAttributesList st)
     {
       SynthesizedXAIFInfo *dsptr = new SynthesizedXAIFInfo();
       next_avail_index = 0;
       next_avail_edge = 0;
       //vv.clear();
       debugMsg(5, "XAIFGlobalTraverse::sageToGraph(non-string)
 needtocallAD is " << needtocallAD);

       dsptr->needtocallAD = needtocallAD;
       return *dsptr;

     }
