Comment:

 This is a duplicate of #11274 and others (panic with `-fdefer-typed-holes`
 and missing instance).

 Already fixed in 8.0.

 I don't think adding another test to the testsuite is necessary.

 For fun, here is a smaller reproducer:

 {{{
 module T10968 where
 f1 = fmap id _
 }}}

 Thanks for reporting.
