-No need to check if a pointer is null before freeing it.

-However if the pointer is still living (for example a global) you should assign NULL to it to avoid bad ram access and random bugs. Accessing a NULL pointer always  gives a segfault, accessing a freed pointer may or may not crash.
-Also fixed a memory leak
