[Freeciv-Dev] civgame-750-hangs.gdb

[Peter Schaefer <schaefer@xxxxxx>]

Here is the trace that shows where it hangs.
Things to fix immediately would be:
- make sure dangerfunct (v=0, m=0, dist=39) advmilitary.c:127  
is not called with a zero value m. ( add a assert(m); there ).

The unit pointer/unit type used is fishy, see punit.

BTW.:
I could only run the program after editing your savefile, I don´t have so many 
nations.
Maybe the nation info should be expanded/ or substituted so that it works, 
instead of relying on a nation index;
I don't know whether the nation id is actually used, guess in the ai setup, and 
in the image selection.
