This is the dreaded syntax parameter bug:

  https://issues.guix.info/issue/27476

which I think is the same as the “info-dir bug”:

  https://issues.guix.info/issue/28144

I had come to believe Guile 2.2.4 addressed these, but lately people
have been reporting similar issues quite frequently, so I guess we have
a problem.

Thoughts?
