Bug #86: Deletion of unnecessary checks before calls of the function "free"
The function "free" is documented in the way that no action shall occur for a passed null pointer. It is therefore not needed that a function caller repeats a corresponding check. http://stackoverflow.com/questions/18775608/free-a-null-pointer-anyway-or-check-first This issue was fixed by using the software "Coccinelle 1.0.4".
