Bug#1075255: matanza: ftbfs with GCC-14

[Matthias Klose]

Package: src:matanza
Version: 0.13+ds2-1
Severity: important
Tags: sid trixie
User: debian-gcc at lists.debian.org
Usertags: ftbfs-gcc-14

[This bug is targeted to the upcoming trixie 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-14/g++-14, but succeeds to build with gcc-13/g++-13. The
severity of this report will be raised before the trixie release.

The full build log can be found at:
http://qa-logs.debian.net/2024/07/01/matanza_0.13+ds2-1_unstable_gccexp.log
The last lines of the build log are at the end of this report.

To build with GCC 14, either set CC=gcc-14 CXX=g++-14 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-14/porting_to.html
