initializeTypeChecker is kicking off work via mergeSymbolTable that ends up pulling on globalObjectType before it's initialized (later in initializeTypeChecker) 😱

@abhaysocialised I still can’t reproduce this—do you have a repo you can share where this is happening?

I'm still seeing this in 4.5.2. Was this merged to that version (I assume so, but wanted to verify).
