A second test rebuild of Vivid Vervet was started last week for all architectures, and is finished for the main component.
Results can be found at
http://people.ubuntuwire.org/~wgrant/rebuild-ftbfs-test/test-rebuild-2015040...
The archive for the test rebuild is https://launchpad.net/ubuntu/+archive/test-rebuild-2015002/
For arm64 and armhf the gcc-4.9 packages are based on the Linaro 4.9-2015.03 release.
Additional build failures for packages in vivid-proposed (not yet in vivid) can be found at http://qa.ubuntuwire.com/ftbfs/
Please help fixing the build failures.
