Bug#957919: w-scan: ftbfs with GCC-10

[Matthias Klose]

Package: src:w-scan
Version: 20170107-2
Severity: normal
Tags: sid bullseye
User: debian-gcc at lists.debian.org
Usertags: ftbfs-gcc-10

Please keep this issue open in the bug tracker for the package it
was filed for.  If a fix in another package is required, please
file a bug for the other package (or clone), and add a block in this
package. Please keep the issue open until the package can be built in
a follow-up test rebuild.

The package fails to build in a test rebuild on at least amd64 with
gcc-10/g++-10, but succeeds to build with gcc-9/g++-9. The
severity of this report will be raised before the bullseye release,
so nothing has to be done for the buster release.

The full build log can be found at:
http://people.debian.org/~doko/logs/gcc10-20200225/w-scan_20170107-2_unstable_gcc10.log
The last lines of the build log are at the end of this report.

To build with GCC 10, either set CC=gcc-10 CXX=g++-10 explicitly,
or install the gcc, g++, gfortran, ... packages from experimental.

  apt-get -t=experimental install g++ 

Common build failures are new warnings resulting in build failures with
-Werror turned on, or new/dropped symbols in Debian symbols files.
For other C/C++ related build failures see the porting guide at
http://gcc.gnu.org/gcc-10/porting_to.html
