TS version is 3.3.3.

I looked at the code and didn't see an obvious cycle (unless a node is somehow its own initializer), so I'm guessing it was just a deep stack of nested initializers.

I didn't see a recent change in this area or a but with these stack frames.

It could be that this is where the stack terminates, but isn't itself cyclical. Is there more context? I cannot seem to see where you found the stack trace.

It looks like this has already been fixed.
