This kind of memcpy() is error-prone. Its replacement with a struct assignment is prefered because it's type-safe and much easier to read.
Found by coccinelle. Hand patched and reviewed. Tested by compilation only.
A simplified version of the semantic match that finds this problem is as follows: (http://coccinelle.lip6.fr/)
// <smpl> @@ identifier struct_name; struct struct_name to; struct struct_name from; expression E; @@ -memcpy(&(to), &(from), E); +to = from; // </smpl>
