Hi Guix! The issue is likely caused by the glibc/fixed graft in (gnu packages base). When this graft is removed, the the path discussed earlier is coherent. Other grafts do not appear relevant.

How exactly does that graft causes the problem? No clue. -- Take it easy, Richard Sent Making my computer weirder one commit at a time.
