  Looks like, at line 2685 of djopt.c (v1.13), a member of "ls" 
(pointer to line_s) is assigned a value but ls itself is never 
initialized.

  [dig dig dig]

  Ahh, in v1.11 of djopt.c, ls is initialized (with a malloc()) during 
declaration.  It was changed on 4/9 by haceaton.  Putting the malloc() 
call back in fixes the problem, but it later blows up in 
add_line_to_corner().  I can look at it further, or send you my PCB 
file, but it bombs in the same manner using the "LED" example.  
Duplicate by loading the example, auto-routing it, then select "auto 
optimize".

  Looks like there's some "work in progress" in there...sorry if this 
is annoying.
