Indeed ;-)

The program has a leak.  Adding

int main()
{
  /* make sure this file exists, otherwise you might get
     a segmentation fault */

  char* TEST_FILE = "test.file";
  char* _1st_line = 0;

  while (1)
    _1st_line = first_line_of_file(TEST_FILE);
  fputs(_1st_line, stdout);
}

and a few "(char*)realloc(...)" to first_line_of_file().
