    #include <stdio.h>
    #include <string.h>
    #include <stdlib.h>

    int
    main(void)
    {
      typedef struct
      {
        char **test;
      }Testing;

      Testing **p;
      p = malloc(sizeof(Testing));
      p[0]->test[0] = malloc(sizeof(Testing));
      strncpy(p[0]->test[0],"Hello World",20);
      printf("%s\n",p[0]->test[0]);

      return EXIT_SUCCESS;
