[svn-r10035] Purpose: Bug fix

Description: On SGI Altix(cobalt) Linux, wrong values were printed out for enum data type
members.  No apparent reason was discovered.

Solution:  use another pointer to the buffer containing the member value.  It seems fix the
problem.

Platforms tested:  cobalt - simple change, where the bug was discovered.
