Can you modify this in your small test program : 
in file src/utils/lib/stubs_c.c
in function value md4_unsafe64_fd (value digest_v, value fd_v, value pos_v, 
value len_v)
(line ~445)

  OS_FD fd = Fd_val(fd_v);
  long pos = Int64_val(pos_v);
to 
  unsigned long pos = Int64_val(pos_v); 

Don't know if this help ( but 
2898944000 is 1010 1100 1100 1010 0110 0000 0000 0000)
