bug in the system

1. An error or glitch within a computer or software system. A bug in the system led to the online retailer leaking the personal data of more than 5 million customers. The phone's snappy UI is fun and intuitive, but some bug in the system seems to be causing it to crash when performing certain actions. We hoped to have the software update out this week, until one of our testers found a pretty significant bug in the system.

2. An acute error, disruption, or oversight within some sociopolitical system. Politicians abusing their power for personal gain is hardly a bug in the system—it's more like a feature at this point. When you refuse to engage with the capitalistic nature of society, you start feeling like some sort of bug in the system. We have to do something about this bug in the system that allows insurance companies to avoid covering certain mental health services.
