Bug#915646: FTBFS: haddock: internal error: internal: extractDecl

[Ilias Tsitsimpis]

Source: haskell-esqueleto
Version: 2.5.3.git20180402-3
Severity: serious
Justification: fails to build from source (but built successfully in the past)

libghc-esqueleto-doc FTBFS with the following error:

   haddock: internal error: internal: extractDecl

This is most probably a Haddock bug[1], fixed in a newer version of GHC.

On the other hand, haskell-esqueleto is not currently needed, is not
part of the latest LTS, and Debian uses an unpublished snapshot of the
code[2]. Should we remove this package from Debian?
