It builds a TRUTH_AND_EXPR with second operand NULL_TREE ... in

#1  0x00000000008a3d96 in find_phi_replacement_condition (loop=0x2ac838a04320, 
    bb=0x2ac8389a7480, cond=0x7fff72b2f308, bsi=0x7fff72b2f2f0)
    at /space/rguenther/src/svn/pointer_plus/gcc/tree-if-conv.c:753
753             *cond = build2 (TRUTH_AND_EXPR, boolean_type_node,
754                             *cond, first_edge->aux);

where first_edge->aux is NULL.
