[Debian-med-packaging] Bug#831131: vsearch: FTBFS with GCC 6: maps.cc:485:3: error: narrowing conversion of '128' from 'int' to 'char' inside { } [-Wnarrowing]

Thu Jul 14 07:29:54 UTC 2016

Source: vsearch
Version: 2.0.0-1
Severity: serious
Tags: stretch sid
User: debian-qa at 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:
- https://wiki.debian.org/GCC6
- https://lists.debian.org/debian-devel-announce/2016/06/msg00007.html
