 On appveyor I had a problem building pretty-show:
 {{{
 --  While building custom Setup.hs for package pretty-show-1.7 using:
       C:\sr\setup-exe-cache\i386-windows\Cabal-
 simple_Z6RU0evB_2.2.0.1_ghc-8.4.2.exe --builddir=.stack-work\dist\ba067387
 build --ghc-options " -ddump-hi -ddump-to-file"
     Process exited with code: ExitFailure (-1073741819)
 }}}

 More details at https://github.com/yav/pretty-show/issues/27 .
 Converting the (otherwise standard) Setup.lhs to a non-literate Setup.hs
 seemed to fix it. Switching to 64-bit GHC seemed to also fix it (the
 Setup.lhs worked with 64-bit GHC).
