Oh wow! That's bad. Let's skip the test and in the meantime I'll make this a P1.

This is an elusive crash. I've gotten it to crash once, but not in the place the bots are crashing, but a bit before. We failed an assertion for the callee of top call frame being a Cell when linking a call. I'm trying to reproduce on a debug build now.

I'm almost certain it's a GC issue, but it's difficult to debug since it's really hard to reproduce.
