[svn-r1021] Purpose:
Bug fix
Problem:
Segmentation fault when attempting to free NULL or uninitialized pointers.
Problem noticed on Linux and HPUX10.20 platforms.
Solution:
Initialialize the pointer to NULL. Execute the "free" statement
upon the condition that the pointer is not equal to NULL (i.e. after the
allocation has taken place.)
Platform tested:
Linux, HPUX10.20, Solaris2.5
