This smells like a problem we just hit with make 4.2.1 in fedora 28
in fstests - the regex expanstion has been screwed up such that
things like [a-z] will match [A-Z] and other things as well. Debian
is unaffected, apparently fedora has a backport of stuff from the
as-yet-unreleased next version of make/glibc. See this thread:

https://www.spinics.net/lists/fstests/msg10200.html

Try setting LANG=C and seeing if the problem goes away....

Cheers,

Dave.
