Hi, During a rebuild of all packages in sid using the gcc-defaults package available in experimental to make GCC default to version 6, your package failed to build on amd64.

You're welcome to contribute! About the archive rebuild: The rebuild was done on EC2 VM instances from Amazon Web Services, using a clean, minimal and up-to-date chroot. Every failed build was retried once to eliminate random failures.
