// Basic test of sharding with a hashed shard key and other unique index
// Does 2 things and checks for consistent error:
//  1.) shard collection on hashed "a", ensure unique index {a:1, b:1}
//  2.) reverse order

// This test triggers a compiler bug that causes a crash when compiling with optimizations on, see
// SERVER-36321.
// @tags: [
//   blacklist_from_rhel_67_s390x,
//   need_fixing_for_46
