            Bug ID: 17844
           Summary: [S390] namespace violation of utmp-functions in
                    utmpx.h, wordexp.h, glob.h
           Product: glibc
           Version: 2.20
            Status: NEW

The linknamespace-test fails on s390-32 with the following namespace
violations:

The commit 4057dc459ae9de59c67628db3db844c7a3765d00 (2008-07-26)
introduced symbol-versioning for those utmp functions with
the macro default_symbol_version, which expands to strong_alias
in the STATIC-case.
But in common-code those funtions are weak aliased.
