This is a message to all like me, who know this game from the 90ies, but were denied lasting fun beyond turn 125 by the game consistently crashing at that turn. The GOG version is playable beyond that point. I just finished a map on turn 188. They seem to have switched the DOSbox exectuable from DOS4GW to DOS32A like mentioned in so many forum posts and comments. So a lot of the reviews, saying that it still crashes at turn 125, seem to be out of date. The memory leak seems still to be there though. In my playthrough it crashd to desktop without any error message once at turn 140 after a 10 hour play session (~70 turns made, if I recall correctly). But after restarting and reloading the save from last turn, I was able to continue and finish the game. So saving at the end of the turn and/or restarting the game every few hours is still advisable.
