[Freeciv-Dev] strange ai behaviour

[banjo <banjo@xxxxxxxxxx>]

hi all

rndCiv 0.8.6 works ok with some rulesets (im trying to isolate what is
causing it to crash the server), but the ai is very strange with for 
example a ruleset created by this command...
./rndCiv.pl -s 120 magic fantasy steampunk asia 20th modern atomic 
FantasyRaces
actually it just segfaulted at turn 137 with

Program received signal SIGSEGV, Segmentation fault.

Since rndCiv builds unusual rulesets, it can be useful for checking
the assumptions the ai is built with.
