Answer 1

I got this kind of error when your trying to call free on a pointer that the address is not at start of block. For example:

 1 #include 
 2 #include 
 3 
 4 int main()
 5 {
 6 
 7    int a; // some integers
 8    int *pi;     // a pointer to an integer
 9    pi =(int*) malloc( 1*sizeof(int) );
10 
11    a = 5;
12    pi = &a; // pi points to a
13    pi++; // pi is not anymore at start
14    free(pi);
15 
16    printf("at the end, we are alived \n"); // this will not be printed
17  
18    return 0;
19 }
