Finally disabled the test in 692c2ad327.
Closing.
Thanks for the report!

The package python-gevent doesn't build on i686-linux, the following

Ran 48 tests in 1.238s
I have created a simple standalone script based on this test case:
import os, tempfile, gevent
fd, path = tempfile.mkstemp('.test')
os.close(fd)
hub = gevent.get_hub()
watcher = hub.loop.stat(path, interval=-1)
hub.loop.update_now()
gevent.spawn_later(0.5, os.unlink, path)
hub.wait(watcher)
print(watcher.attr)
print(watcher.prev)
After adding a (delete 'check) to python-gevent's arguments, we observe
the following:
% ./pre-inst-env guix environment --ad-hoc python python-gevent -- python3 ~/tmp/gevent-test.py
None
os.stat_result(st_mode=33152, st_ino=44162375, st_dev=2052, st_nlink=1, st_uid=1000, st_gid=1000, st_size=0, st_atime=1595787602, st_mtime=1595787602, st_ctime=1595787602)
% ./pre-inst-env guix environment --system=i686-linux --ad-hoc python python-gevent -- python3 ~/tmp/gevent-test.py
os.stat_result(st_mode=1000, st_ino=0, st_dev=189675956338688000, st_nlink=1000, st_uid=0, st_gid=0, st_size=6853855360088801280, st_atime=1595787555, st_mtime=0, st_ctime=-2)
os.stat_result(st_mode=33152, st_ino=2052, st_dev=2052, st_nlink=1, st_uid=1000, st_gid=1000, st_size=17592186044416, st_atime=1595787555, st_mtime=1595787555, st_ctime=0)
Namely, the i686 variant returns entirely bogus values.
I have tried reproducing this in a Guix-less environment in a Docker
container based on the i386/debian:bullseye image, but I haven't had any
luck.
