Building base-noprelude: haskell-nix.snapshots."lts-14.15".base-noprelude.components.library
fails during haddockPhase:

Probably related to #359

@balsoft would you mind taking a look?

[balsoft]

Yep, this is my fault. I'll look at it right now.

There is a commit by @hamishmack in a separate branch which modifies the haddock phase, maybe it's fixed there: bebd3f1

[zhenyavinogradov]

There are no problems with that commit applied, this issue should be closed when the branch is merged

[hamishmack]

#371 has been merged

FYI, when using a Cabal version before 2.4 this gets triggered by the cabal bug haskell/cabal#5232 . I have seen this happening e.g. for fail and bytestring-builder. I guess it is not worth working around this in haskell.nix, as only old Cabal versions are affected.

For completeness, here is an example log:
