Using current cabal at c2dfc33 built with GHC 8.0.2,
configuring for use with GHC ghc-8.2 branch at b3f7e9b54d9f36938effd265c84d5567b34c905b, with a brand new install.

The commit you referenced is fairly old (Sep 13, 2016) and I couldn't repro using any of:

• Cabal at 65879f4bf3aa288e77e488c135b20a28ba8c6efb, 20de0bf or most recent Cabal from @hvr's PPA
• With GHC 8.2.0.20170313 from @hvr's PPA
• On ghc-exactprint.

Here is an example succeeding run:

ezyang@sabre:~/Dev/labs/ghc-exactprint$ /opt/cabal/head/bin/cabal new-configure --enable-tests -fdev --with-compiler=ghc-8.2.1 --allow-newer

Can you try again with a more recent cabal-install version?

[alanz]

Oops, the cabal version in question is actually 8d3e120

Not sure how I got that hash in my report.

[alanz]

Ok, it seems to be related to other directories used as subprojects

My cabal.project has

packages: .
     ../../ekmett/comonad
     ../../bgamari/hashable
     ../../ekmett/semigroupoids
     ../../phadej/doctest

-- doctest needs branch static-flags-802-fix

where each repo matches the github 8.2 branch version.

If I comment out all the subpackages except '.' then it configures fine, but the build fails on comonad, as expected

With cabal version 6316102 I'm getting two similar assertions, but only when I use the following cabal.project.local file:

jobs: 1
flags: +with_expensive_assertions
profiling: False
library-profiling: False
tests: False
coverage: False
library-coverage: False
optimization: False
documentation: False

package *
  documentation: True
  library-profiling: False

Here's how to reproduce:

git clone git@github.com:LambdaHack/LambdaHack.git
cd LambdaHack
git checkout 16e5632a10b116905e499f2dd83ca21d0a0be261
~/teeeeeeeeee/LambdaHack$ cabal new-install -j1 .
