I just submitted a re-build of ODB for GCC 4.9.2 in rawhide ( http://koji.fedoraproject.org/koji/taskinfo?taskID=8051892 ) and it ran into an issue ( http://koji.fedoraproject.org/koji/taskinfo?taskID=8051895 ).

I don't have access to a machine with rawhide to do any more debugging, but I've included the pertinent output below and what's the recommend path for working on getting this resolved?

Thanks,
Dave
