[svn-r9201] Purpose:

bug fix

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)


Platforms tested:
Cray T3E (read data from linux)
linux
solaris
aix
