Civ 1 - The Great Library Destruction Bug

In Sid Meyer's Civilization 1, from the 90s, you can encounter a bug.
It happens when the Wonder of the World, called the Great Library, is built in a city that later gets destroyed (or taken over by the Barbarians).
All destroyed Wonders of the World gets owned by the Barbarian, and the Great Library starts to give out knowledge, even advanced stuff.
It for me, always crashes soon thereafter, with an error saying it tries to do division on an Integer by zero (not allowed in math)
All this is shown in this video, enjoy!

Wow! Years of playing Civ and I've never seen this. This is crazy 😂

That's why I expect FreeCiv to be more boring due to be open source than original civ 1 game. Once I built the Great Library and let barbarians take it. Sometimes I spied the city screen but they didn't produce anything except legions for a long time (they had enough time to get technologies from the Library). I only had 'Sneak attack of barbarian forces' bug several times.
