+// There is an ICE somewhere in type normalization, and we are hitting it during
+// the MIR inlining pass on this code.
+//
+// Long term, we should fix that ICE and change the compile-flags for this test
+// to explicitly enable MIR inlining.
+//
+// Short term, we are diabling MIR inlining for Rust 1.64-beta, so that we avoid
+// this ICE in this instance.
