Bug#831146: wvstreams: FTBFS with GCC 6: streams/wvstream.cc:1111:69: error: no matching function for call to 'WvStream::select(int, IWvStreamCallback&, IWvStreamCallback&, IWvStreamCallback&)'
Source: wvstreams
Version: 4.6.1-9
Severity: serious
Tags: stretch sid
User: debian-qa@lists.debian.org
Usertags: qa-ftbfs-20160713 qa-ftbfs
Justification: FTBFS with GCC 6 on amd64
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. For more information about GCC 6 and Stretch, see:

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.
