  * Test for type families related panic
  
  The test program should be rejected but not with a panic. I haven't added a
  .stderr file because I don't know what the error message should be.

    A ./tests/ghc-regress/indexed-types/should_fail/Simple14.hs
    M ./tests/ghc-regress/indexed-types/should_fail/all.T +1
