:    { d_list_proc, 450, 50, 120, 330, 255, 0,  0,  0, 0, 0, NULL },

I'm pretty sure this line is your problem.  The NULL at the end shouldn't
be NULL, it should be a function which returns the stuff that's going to
be in the list.  I can't remember the exact syntax, but take a look at
allegro.txt and it gives a good explanation of what the function has to
do.
