Oh, sorry, I mis-read something 🐣

A divide and conquer approach would otherwise be to enable() and 
disable() GC at various places to narrow it down. Or even do a 
collect() and look at addrOf as stated earlier.

Would be good to know if there really is a bug in the GC or not. 
I suspect not, but you can't know for sure until you try.
