The #wontfix list about the gc is labled as ub and is all about 
pointers(instead of #wontfix and documenting real issues); and 
this is a fundamental limitation of a gc that scans pointers

Why all`y`alls safetyphiles ignoring me quote`n the spec. Theres 
no clarity for any pointer tricks that survive contact with the 
enemy(the gc) so I dont know what I actaully want to know, but 
its pretty clearly going to be programmertime expensive to try to 
find any.
