title: Malloc don't segmentation fault
body: <p>I have this code:</p>
  
  <pre><code>char *test = malloc(sizeof(char) * 1);
  test[0] = 't';
  test[1] = 'e';
  test[2] = 's';
  test[3] = 't';
  test[4] = '\0';
  printf("%s", test);
  </code></pre>
  
  <p>I malloc my test with one sizeof char.
  But when I run this program, my program don't segfault. Why ? ..</p>
  
  <p>Thanks you !</p>
