Author:   Bill Ross
Date:     June 4, 1999

Programs: Leap

Severity: Mild

Description: Adding a redundant bond to a residue template in a
	     prep.in LOOP section will cause Leap to exit when 
	     loading an instance of the residue via loadpdb.

Fix: Make the following change to amber.c:

*** OLD amber.c
--- NEW amber.c
