RedHat 8.1 uses glibc 2.3 with the NPTL thread package instead of
the linuxthreads thread package and valgrind is therefore highly
unlikely to work with threaded programs under RedHat 8.1 until some
work is done to make it handle the changes to threading.

The fact that this assertion is talking about segment selectors
suggests that thread local storage is involved, and hence this is
probably a threading related problem.

Before anybody worries about the update to glibc 2.3.2 that was
released for RedHat 8.0 the other day, that version was built with
linuxthreads so there is no problem there.
