Subject: guix-core failed to build: return used outside of 'with-monad'
Date: Mon, 04 Feb 2019 14:37:58 -0500

Hydra is currently unable to produce new evaluations of 'master', due to
a build failure in the 'guix-core' derivation, specifically:

  /gnu/store/50lyirc9g8z8qv9r860hp00d5qm5xijd-guix-core.drv

See below for the tail of the failed build log.

Hi!

For the record, this was fixed in
61a8c9300daeb730fe5094f889bf13241942be84, which made it into 2.9/3.0,
and 2dccec9f553776656d9378e2315ad32d2e55286b, which made it into 2.2.5.

Closing!  :-)

Ludo’.
