Package: Emacs
Version: 26.0.50

It looks like the new records-based code introduced a bug in the way
records are handled as keys in hash-tables when the test is `equal`:

    (progn
      (cl-defstruct sm-foo a b)
      (setq sm-hash (make-hash-table :test 'equal))
      (puthash (make-sm-foo :a 4 :b 6) "test1" sm-hash)
      (puthash (make-sm-foo :a 4 :b 6) "test2" sm-hash)
      (hash-table-count sm-hash))

this code return 2 here instead of 1.  Lars, could you take a look at it?
