Sigh.
Yes, I reported some of them. Some got fixed, some got ignored. You can search my name on openbsd-tech and misc for proof.
I found more, but the ratio of ignored to fixed is too high to bother.
Years ago I also fixed bugs in the MPLS implementation. Like bugs I found immediately upon using the feature. (IIRC e.g. implicit null was erroneously pushed explicitly)
I can't find the cat bug, mind linking to it for my peace of mind?
The find bug was merged the next day from what I could tell.
