+// Regression test for #34991: an ICE occurred here because we inline
+// some of the vector routines and give them a local def-id `X`. This
+// got hashed after codegen (`hir_owner(X)`). When we load back up, we get an
+// error because the `X` is remapped to the original def-id (in
+// libstd), and we can't hash a HIR node from std.
