noone ever told them that even the eldest C can be used in a safe
way;

 

Perhaps we have different meanings of the word safe.

    void foo(char *p) { /* interesting stuff here */ ; free(p); }

    void bar() { char *p = malloc(20);

        foo(p);

        printf("foo is %s\n", p);

        foo(p);

    }

Why should I have to think about this code when the language already knows what is wrong.
