It caused by a cycle query:

// for `{impl#0}::next`
convert_impl_item 
   ->  rustc_middle::fn_sig 
   -> execute_job 
   -> rustc_hir_analysis::collect::fn_sig 
   -> lookup_inherent_assoc_ty 
   -> sup 
   -> variances_of 
   -> rustc_middle::fn_sig

There's a related bug to this (I believe by involving some traits with associated types) that I would like to report, though I was able to raise mine on Stable (1.70.0) without using the feature flag. Should I make a separate bug report or attach it here?
