Right. I was focusing on the point that what matters is the copyright notice. While your pointing out that you can relicense MIT code because MIT is so permissive, while you can relicense GPL to almost nothing, as it’s not compatible with most other licenses. However that’s kinda moot, you couldn’t include GPL code into an MIT licensed project anyway due to the copyleft.
(Thanks for the “ingenuous” correction, I did indeed - to my non-natively speaking brain the “in” acted as a negation to the default “genuous”, which yeah, just isn’t a thing of course)
Technically that wasn’t the initial entrypoint, paraphrasing from https://mastodon.social/@AndresFreundTec/112180406142695845 :
It started with ssh using unreasonably much cpu which interfered with benchmarks. Then profiling showed that cpu time being spent in lzma, without being attributable to anything. And he remembered earlier valgrind issues. These valgrind issues only came up because he set some build flag he doesn’t even remember anymore why it is set. On top he ran all of this on debian unstable to catch (unrelated) issues early. Any of these factors missing, he wouldn’t have caught it. All of this is so nuts.
