[svn-r9203] Purpose:
bug fix


Description:

Description:
the dataset region reference data was not portable between the Cray T3E and other machines




Solution:
this was due to the fact that the  buffer to store the heap ID and index was using a sizeof(int) for its
size


 4 is used instead of sizeof(int) to permit portability between
   the Crays and other machines (the heap ID is always encoded as an int32 anyway)




Solution:

Platforms tested:
linux
aix
solaris



Misc. update:
