I have the following code working correctly on a spark station in Unix.  I want
to run it on my Mac IIcx in Think-C so I can get out of my profs office and do
the work for him at my house.  Can someone please tell me what's wrong.

  fp = fopen("DATA","r");
  fscanf(fp,"%d %d %d ",&(in->num_feeder),&(in->num_place),&(in->preamble));
  printf("# feeders = %d, # placements = %d, preamble = %d.\n",in->num_feeder,
          in->num_place,in->preamble);

/** this part is working.  the values printed out are correct **/

  in->x = (int *) malloc(sizeof(int)*(in->num_place+1));
  in->y = (int *) malloc(sizeof(int)*(in->num_place+1));
  in->feeder = (int *) malloc(sizeof(int)*(in->num_place+1));
  in->rotation = (int *) malloc(sizeof(int)*(in->num_place+1));
  in->board = (int *) malloc(sizeof(int)*(in->num_place+1));
  in->id = (int *) malloc(sizeof(int)*(in->num_place+1));
  in->speed = (double *) malloc(sizeof(double)*(in->num_feeder+1));
  bin->x = (int *) malloc(sizeof(int)*(in->num_place+1));
  bin->y = (int *) malloc(sizeof(int)*(in->num_place+1));
  bin->feeder = (int *) malloc(sizeof(int)*(in->num_place+1));
  bin->rotation = (int *) malloc(sizeof(int)*(in->num_place+1));
  bin->board = (int *) malloc(sizeof(int)*(in->num_place+1));
  bin->id = (int *) malloc(sizeof(int)*(in->num_place+1));
  bin->speed = (double *) malloc(sizeof(double)*(in->num_feeder+1));
  bin->rotate = (double *) malloc(sizeof(double)*(in->num_place+1));

  for (node=0;node<in->num_place;node++) {
    fscanf(fp,"%d %d %d %d %d %d ",&(in->id[node]),&(in->board[node]),
       &(in->feeder[node]),&(in->x[node]),&(in->y[node]),
       &(in->rotation[node]));
    printf("node # = %d, id # = %d, board # = %d, feeder # = %d, x = %d, y = %d, rotation = %d.\n",
            node,in->id[node],in->board[node],in->feeder[node],
            in->x[node],in->y[node],in->rotation[node]);
  }
/**  this is where the problem is.  the values printed here are wrong, and my
Mac hangs up with the message "bomb" in the debugger  **/

the data file looks like this

I just started programming C on the Mac, and I don't have that much under Unix.
Can someone please tell me what seems to be wrong.

Thanks,
