Description: tleap causes a segmentation fault when removing atoms;
             xleap causes a segmentation fault when Erasing atoms in the
             Unit Editor.

Fix:  apply the following patch to amber7/src/leap/src/leap/atom.c

------------------------------------------------------------------------------

      for ( i=0; i<iBonds; i++ ) {
  	aBond = aaBond[i];
  	VP1(( "Breaking bond: %s - %s\n",
+ 		sAtom1,
  		sContainerFullDescriptor( (CONTAINER)aBond, sAtom2 ) ));
  	AtomRemoveBond( aAtom, aBond );
      }

Temporary workarounds: Delete all bonds to an atom before removing it.
