You will need to wait a bit to see heap overflow and icr crash

what? lol. I've never even seen that error before. Any idea what that even means?

Ah, that seems to be a bug in Crystal https://github.com/crystal-lang/crystal/issues/5239. I'm not an expert in this, but it looks like a heap overflow related problem. GC suggests to increase some configuration variables because of overflow.
