Author:   Bill Ross
Date:     7/30/99

Programs: xleap

Severity: Unknown

Description:  This is an error discovered by a memory use debugger, Purify.
		It could easily crash the program in the Unit Editor on
		'Relax selection'. In the absence of frequent crashes, it
		appears that there may be no consequence of this bug..

Fix: Make the following change to minimizer.c:
-----------------------------------------------------------------------------
*** OLD minimizer.c
--- NEW minimizer.c

                  /* Conjugate gradient minimization, evaluate the function */
