 The most recent completed run of `validate-x86_64-linux-unreg` on Circle
 CI (​https://circleci.com/gh/ghc/ghc/7733) shows 13 unexpected failures
 and 1 unexpected pass.

 All failures but `T7040_ghci` happen in the debug validation job too (see
 #15466). `recomp007` doesn't fail here and `T7040_ghci` "replaces" it. I'm
 therefore only including the details for `T7040_ghci` here, as you can
 find out everything about the other faiilures in #15466.

 }}}

 I suspect this is one of those cases where ghci can't load the module
 because of unboxed sums and what not, I havent' checked yet, but we were
 seeing that type of error.
