Catch Go bugs that fuzzing misses with Gemini and a constraint solver- Google Developers Blog

In 30 Sekunden

Was passiert ist

Google used Gemini 4 Argon and Z3 constraint solver to find Go bugs that fuzzing misses by analyzing compiled machine code.

Warum es zählt

Go developers maintaining complex parsers or slice-heavy code should consider this when standard fuzzing and testing leave them uncertain about bounds-check safety.

Achtung

The LLM-generated solver model is not formally sound; it finds real bugs only because go test verifies each crash, but unsat answers mean maybe correct, not definitely correct.
