Programs: sander
                                                                                
Description: The minimization initialization in sander can attept a divide
             by zero.  No use is made of the returned value, so this is
             generally innocuous, but it can cause problems if a fatal
             exception is raised as a result.
                                                                                
Fix:  apply the following patch to amber9/src/sander/runmin.f
