The test was previously always executed after the if containing that branch, but it was always false unless the if branch was taken. The semantic match that finds this problem is as follows: (http://coccinelle.lip6.fr/) // @r disable braces4@ position p1,p2; statement S1,S2; @@ ( if (...) { ... } | if (...)
