[QUOTE="The Real OS/2 Guy, post: 1693531"] Wrong. It occures undefined behavior when you forget to include stdlib.h. You hides the diagnostic saying that you tries to convert int to a pointer throu casting the value the compiler things it were int to a pointer. The same bug as above - resulting in undefined behavior. That's fine - but lets q hold an indetermined value (the pointer in it points to somewhere but not to an address guilty for your program) after free. [/QUOTE]
