Package: python-cffi
Version: 1.4.2-2
Severity: important
User: debian-...@lists.debian.org
Usertags: ftbfs-gcc-6 gcc-6-shift-negative-value
This package fails to build with GCC 6. GCC 6 has not been released
yet, but it's expected that GCC 6 will become the default compiler for
stretch.
Note that only the first error is reported; there might be more. You
can find a snapshot of GCC 6 in experimental. To build with GCC 6,
you can set CC=gcc-6 CXX=g++-6 explicitly.
You may be able to find out more about this issue at
