I am not sure if I can help, but at least, there are a couple of questions.
1) I suppose your file is the one called my_scene.pov? Can you tell us what 
is written at and around line 665798 of that file? I assume it refers to a 
finish{} statement...
2) You use 15-20 copies of a simple DNA double helix. Are they referenced 
copies? or is the complete code just copied 15-20 times? That would account 
for the large file (and perhaps for the parse error, but I am not sure). To 
make a referenced copy of your helix, do the following:

#declare My_helix =
union {
  my DNA code
}
object {My_helix}
object {My_helix
  translate <my_x, my_y, my_z> or whatever transformation you need....
}
etc....
