FYI, I noticed this because it makes the coreutils printf-surprise regression test fail. Probably just fixed by this upstream commit: http://sources.redhat.com/git/gitweb.cgi?p=glibc.git;a=commitdiff;h=a5fb313cb7b7e692fd4684916aaa98e03ec7e8b6 glibc-2.14.90-16 has been submitted as an update for Fedora 16. https://admin.fedoraproject.org/updates/FEDORA-2011-15723 This package has changed ownership in the Fedora Package Database. Reassigning to the new owner of this component. Package glibc-2.14.90-16: * should fix your issue, * was pushed to the Fedora 16 testing repository, * should be available at your local mirror within two days.
