I want to hear a war story of someone starting from a React bug report, reducing it to pure JS, fighting through the Chrome build process, isolating the v8 JIT bug, producing a patch, and going on to a successful compiler career.

Heh, I could almost tell that story. We had a bug in a React app that started when a new Chrome release came out. I boiled it down to a small piece of JS that V8 was clearly misinterpreting and which looked like it might be memory corruption in the JITed code. Yep, I got a Chrome build going and was tracing through to see what was going on ...

... but I'd also submitted the JS fragment to Chrome, of course. They ended up flagging it as a high security bug and, not surprisingly, beat me to a fix.

So I never got as far as making a patch, which I guess is why I still don't have a successful compiler career.

I did get a $1k security bounty from Google, though, so that was cool.

Let me see if I can google the bug report. This is it: https://bugs.chromium.org/p/chromium/issues/detail?id=282736

Ah, report reminds me that at that point, the app was all knockout.js. We ported it to a knockout/React hybrid later.
