I've personally verified and approved a actual bugfix made by a LLM. Wasn't the trickiest nor most severe bug I've ever seen, but it had slipped through the cracks in our testing and review process, and the LLM caught it.

Nothing snake oily here.

Also: What compiler are you using that's giving you false positive warnings?

I have never heard of a false positive warning nor error from a compiler, but perhaps you're using some weird tooling I'm not familiar with?
