try making sure that you have ended each line with a newline
(there's only three lines of data in this message, the second
is 138 characters wide and has eight numbers).

The problem here is that sscanf did not convert four arguments.
(see src/mapdev/v.transform/get_coor.c and sscanf(3))

--Darrell

from get_coor.c:

if ( fgets (buff, sizeof (buff), fp) == NULL)
  break;
 
if ( sscanf (buff, "%lf %lf %lf %lf", &ax[i], &ay[i], &bx[i], &by[i])  !=  4)
{
  fprintf (stderr, " ERROR:  Reading coordinates from file\n.");
  return (-1);
}
