We are working to migrate binutils version 2.25.90.20151209-1 into testing asap. If everything goes well it should be the case after the 13:52 UTC dinstall run, so a few hours after that on the mirrors. In the meantime fetching and installing this version from sid, should solve the issue. Aurelien -- Aurelien Jarno GPG: 4096R/1DDD8C9B aurel...@aurel32.net http://www.aurel32.net
