[Flightgear-devel] crash in AI traffic

[<csa...@gm...>]

Hi!

Helijah has run into a crash. Gdb backtrace here:
http://pastebin.ca/589461 (no debug symbols unfortunately)

Looks like the "next" waypoint is null.
As a quick and dirty fix I came up with this:

     if (fabs(speed_diff) > 10) {
         prevSpeed = speed;
-        fp->setLeadDistance(speed, tgt_heading, curr, next);
+        if (next) fp->setLeadDistance(speed, tgt_heading, curr, next);
     }
 }


This is probably not the right way to fix it, somebody please have a look.

Thanks,
Csaba
