A simplified version of the semantic patch that finds this problem is as
follows: (http://coccinelle.lip6.fr/)
// <smpl>
@r1@
statement S;
position p,p1;
@@
S@p1;@p
@script:python r2@
p << r1.p;
p1 << r1.p1;

if p[0].line != p1[0].line_end:
        cocci.include_match(False)
@@
position r1.p;

-;@p
// </smpl>
