Bug#984416: xmltooling: ftbfs with GCC-11

[Matthias Klose]

Package: src:xmltooling
Version: 3.2.0-2
Severity: normal
Tags: sid bookworm
User: debian-gcc at lists.debian.org
Usertags: ftbfs-gcc-11

[This bug is not targeted to the upcoming bullseye release]

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-11/g++-11, but succeeds to build with gcc-10/g++-10. The
severity of this report will be raised before the bookworm release,
so nothing has to be done for the bullseye release.

The full build log can be found at:
http://people.debian.org/~doko/logs/20210228/filtered/gcc11/xmltooling_3.2.0-2_unstable_gcc11.log
The last lines of the build log are at the end of this report.

To build with GCC 11, either set CC=gcc-11 CXX=g++-11 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-11/porting_to.html

GCC 11 defaults to the GNU++17 standard.  If your package installs
header files in /usr/include, please don't work around C++17 issues
by choosing a lower C++ standard for the package build, but fix these
issues to build with the C++17 standard.
