kg · 2021-06-05T04:05:57Z

Does this seem like a regression? Or just an existing bug we weren't noticing?

lewing · 2021-06-05T04:40:04Z

My first check around continuations would be GC.

kg · 2021-06-05T04:51:14Z

Yeah, it's quite likely this is a GC issue, but also the arguments to this function are marked as non-nullable when they're nullable, so it's possible a null is making its way in from the JS side. The code doesn't handle that.

kg · 2021-06-08T02:15:10Z

I spent a while trying to reproduce this but can't get it to fail, it must rely on something about the CI hardware. I'll have to just audit and rework the code.
