I think this call might be introducing a cycle, which manifests as an .unwrap() ICE. Can you check if calling tcx.lookup_stability(def_id) also hits it?

Yeah, that's what I was vaguely thinking. tcx.lookup_stability isn't what we want either, it calls eval_stability internally and emits an error if the DefId is unstable (definitely not what we want).check_stability, lookup_stabilty is the low-level one 🤦) I'm not sure how to fix the cycle.

@estebank The offending code is in let is_staged_api = self.lookup_stability(def_id.krate.as_def_id()).is_some();
if !is_staged_api {
return EvalResult::Allow;
}The I have no idea on how to fix this. |

Let's land the typeck part of this for now and keep investigating the resolve version. It's likely we'll have to add some tracking to |

@estebank Sure, I'm happy to land just the typeck part, I'll be looking into the resolve part a bit (not sure the fix is easy). |

Fixes #109177
Don't display typo suggestions for unstable things, unless the feature flag is enabled.
AFAIK, there are two places this occurs:
rustc_resolve: before type checking, effectively justFnCtxt::Free.rustc_hir_typck: during type checking, forFnCtxt::Assoc(..)s.The linked issue is about the latter, obviously the issue is applicable to both.
