  The storage located at 2BFFF510 was gotten with a BSS1_GetStg()
  from
  kraaamss.cpp's groupDataRowsToBuffer().  The statement located
  at line 384
  requested the storage:
  
    rowBuffer = (char *)BSS1_GetStg(maxBufferSize);
  
  The statement located at line 375 calculates the size of storage
  to be requested.
  
    maxBufferSize = sampleSize + cacheDataSize + rowLen;
