Description

    if (best != NULL && best_value >= game.info.culture_vic_points
        && best_value > second_value * (100 + game.info.culture_vic_lead) / 100) {

If second_value > 7158277, the first multiplication exceeds 2**31 and overflows.

The back story - I made the history_interest_pml value too big in my custom ruleset, forgetting about what happens with compound interest. Culture values this big would never happen with supplied rulesets, but this should still get fixed.
