+//! Regression test for <https://github.com/rust-lang/rust/issues/133606>.
+//!
+//! In rare cases, all of a function's coverage spans are discarded at a late
+//! stage during codegen. When that happens, the subsequent code needs to take
+//! special care to avoid emitting coverage metadata that would cause `llvm-cov`
+//! to fail with a fatal error.
+//!
+//! We currently don't know of a concise way to reproduce that scenario with
+//! ordinary Rust source code, so instead we set a special testing-only flag to
+//! force it to occur.
+
+//@ edition: 2021
+//@ compile-flags: -Zcoverage-options=discard-all-spans-in-codegen
+
+// The `llvm-cov` tool will complain if the test binary ends up having no
+// coverage metadata at all. To prevent that, we also link to instrumented
+// code in an auxiliary crate that doesn't have the special flag set.

+// This caused a regression in a crater run in #132325.
+//
+// The underlying issue is a really subtle implementation detail.
+//
+// When building the `param_env` for `Trait` we start out with its
+// explicit predicates `Self: Trait` and `Self: for<'a> Super<'a, { 1 + 1 }>`.
+//
+// When normalizing the environment we also elaborate. This implicitly
+// deduplicates its returned predicates. We currently first eagerly
+// normalize constants in the unnormalized param env to avoid issues
+// caused by our lack of deferred alias equality.
+//
+// So we actually elaborate `Self: Trait` and `Self: for<'a> Super<'a, 2>`,
+// resulting in a third `Self: for<'a> Super<'a, { 1 + 1 }>` predicate which
+// then gets normalized to  `Self: for<'a> Super<'a, 2>` at which point we
+// do not deduplicate however. By failing to handle equal where-bounds in
+// candidate selection, this caused ambiguity when checking that `Trait` is
+// well-formed.
