[Message part 1 (text/plain, inline)]

Hello,

On the current 'master' branch, using an inferior in a manifest will
cause a crash in 'compute-guix-derivation' as reported in
<https://lists.gnu.org/archive/html/help-guix/2020-04/msg00010.html>.

It can be reproduced by taking the inferior example from the manual:
https://guix.gnu.org/manual/en/guix.html#Inferiors

..and running 'guix build --no-grafts -n -m inferior-example.scm'.

I've attempted to bisect it, but it is difficult because once you have
successfully passed 'compute-guix-derivation', the problem is no longer
reproducible, even on known "bad" commits.  So for every successful test
a new commit/channel must be chosen.

Here is a backtrace from a bad commit:

Hi Marius,

This is now fixed in 8ed597f4a261fe188de82cd1f5daed83dba948eb.

Thanks for investigating!
