I really need some help with memory leaks. I compiled code.c (shown bellow) with gcc -Wall -pedantic -Wno-long-long -g -std=c99 -fsanitize=address code.c and run it, Address Sanitizer not detect memory leaks.

How to detect these memory leaks, please?

Here is my code (code.c):

#include <stdio.h&gt
#include <stdlib.h>

#define

Hmm, works here

$ gcc -Wall -pedantic -Wno-long-long -g -std=c99 -fsanitize=address code.c

$ ./a.out
