bug#34402: Inferior channel (I believe 'inferior-for-channels' function specifically) sometimes fails

There’s nothing following the colon above?

I wonder if it could be <https://issues.guix.info/issue/34016>, though
I’ve never experienced it in ~/.cache/guix, despite using ‘guix pull’ &
co. a lot.

Next time this happens, could you run:

  strace -s 100 -o log guix package -n -m example-inferior.scm

and post the last few hundred lines of ‘log’?

Thanks,
Ludo’.
