I ran a bunch of different compilers on it, including some open source ones.
Some of them failed some tests, and it was natural to have my LLM (Claude Fable 5) root-cause the issues, and to double-check my test bench wasn't to blame.
But now I stood with all these patches that I couldn't just throw at the upstream maintainers all at once. I ended up just filing a few issues and moved on to other things.
It felt weird to just file issues when my LLM had already spent a lot of time root-causing and fixing the issues. But then, maybe they could just have their LLMs do the same.
Still not sure if it was the right call?
