I don't have any data for what can be an issue here, unfortunately - it just doesn't load.

I'm at my tsc exploration, once again - I've been recording it today with success to create this repro case. But this one has to hit some different paths that make Replay choke:

@Andarist curious what @bhackett1024 finds, but yeah - it looks like there were some FatalErrors on our end while replaying.

It looks like node OOM'ed in the GC when replaying. I'm not super familiar with V8's GC, but I think the problem is that it was trying to promote an object and couldn't copy it to the old space because of a limit on the maximum size of the old space. I added an attempted fix and some diagnostics in 11b15c6, so things should be working better in the latest node (run replay-node --update to update), and if not we'll have more information to track down what's going wrong.
