Comment (by alpmestan):

 I ran the test with a (quickest flavoured) GHC from commit
 a32c8f7514c8192fa064537fb93d5a5c224991a0, and I do get:

 {{{
 Unexpected passes:
    typecheck/should_compile/T14732.run  T14732 [unexpected] (profasm)
 }}}

 I'll change that expectation in a new diff soon and close this ticket when
 it's merged.
