From: Julia Lawall <julia@xxxxxxx> The variable isi might be null or might be freed at the point of the call to clk_put. pclk contains the value that isi->pclk is expected to point to. The semantic match that finds this problem is as follows: (http://coccinelle.lip6.fr/) // <smpl> @r@ expression E, E1; identifier f; statement S1,S2,S3; @@ if (E == NULL) { ... when != if (E == NULL || ...)
