I linked you to the gc #wontfix list, it's explicitly the magic 
words "UB".

Idk what's actually happens(ub isn't a useful distinction), 
someone would have to extensively test it, but it's expressly not 
"do whatever" someone must've tried the xor linked list and found 
it doesn't work in some case.

An invalid pointer outside common use patterns could confuse the 
GC and some invalid pointers are *known* to confuse the GC(they 
should've keep the code rather then their wontfix list *tsk*)
