Context:

The highlighted line of code below is the trigger point of this particular Alpine 3.6 obsolete weakness.

 void
paned_close_childs (void)
{
  guint i;
  struct shmid_ds buf;
  gboolean is_running = TRUE;

  if (tabs[1].pid != -1)
    kill (tabs[1].pid, SIGUSR2);
  if (tabs[2].pid != -1)
    kill (tabs[2].pid, SIGUSR2);

  /* wait for stop subprocesses */
  while (is_running)
    {
      is_running = FALSE;
      for (i = 1; i <= 3; i++)
        {
          if (tabs[i].pid != -1 && kill (tabs[i].pid, 0) == 0)
            {
              is_running = TRUE;
              break;
            }
        }
      usleep (1000);
    }

  /* cleanup shared memory */
  shmctl (tabs[0].pid, IPC_RMID, &buf);
  shmdt (tabs);
