        ^^^^^^^^^^^^^^^
You have commited the dreaded C string memory allocation error.
Your problem is analogous to the following:

char *p;

strcpy(p, "BLOW AWAY SOME MEMORY, HOPEFULLY YOUR OS HAS MEM PROTECTION");

You need to allocate space for each pointer.

E.g.  line[1] = malloc(strlen(str) + 1);	/* Normally called strsave() */
      strcpy(line[1], str);

OR, you could declare a 2 dimensional array. (if you know in advance how big
everything is going to be.)

Hope this helps.
