expected usize, got UnevaluatedConst#116186expected usize, got Const#113021This issue arises due to the creation of a fixed-length pattern, as a result of the mir body corruption. The corruption taints
tcx.eval_to_allocation_raw, causing it to return AlreadyReported. Consequently, this prevents len.try_eval_target_usizefrom evaluating correctly and returnsNone. Lastly, it results in the return of[usize; min_len].To rectify this issue, my approach is that to return unfixed when encountering
ErrorHandled::Reported. Additionally, in instances ofErrorHandled::TooGeneric, the previous logic has been reinstated.
