Once I was working with a database with large integer ids loading them through json and showing them in the browser. There was a bug where ids didn't match when updating a record. The issue was that the json decoder for Javascript didn't handle large numbers, so an id like 12345678901234567 would show up as 12345678901234568. That was fun to debug.
