Alex has posted http://review.whamcloud.com/6064 for this issue.

Can't reproduce the failure. Not seen if I configure and build with --disable-server on RHEL 7 Alpha, which has gcc 4.7.2. Suspect the reported failures are in server only code.

Can't configure and build without using --disable-server as there isn't any ldiskfs patch series for the 3.7.0 kernel in RHEL 7.
