Maybe. Or this is another case of what plagued libreoffice and was worked around with https://salsa.debian.org/libreoffice-team/libreoffice/libreoffice/-/blob/master/patches/gcc16.diff?ref_type=heads#L59 ff. and
See also upstreams https://gerrit.libreoffice.org/c/core/+/202511/comments/b6a92d32_0c72b450 and following comments... And indeed the same happens: checking how to run the C++ preprocessor... g++ -std=gnu++11 -E checking for ld used by g++ -std=gnu++11... /usr/bin/x86_64-linux-gnu-ld -m elf_x86_64 checking if the linker (/usr/bin/x86_64-linux-gnu-ld -m elf_x86_64) is GNU ld... yes checking whether the g++ -std=gnu++11 linker (/usr/bin/x86_64-linux-gnu-ld -m elf_x86_64) supports shared libraries... yes checking for g++ -std=gnu++11 option to produce PIC... -fPIC -DPIC checking if g++ -std=gnu++11 PIC flag -fPIC -DPIC works... yes checking if g++ -std=gnu++11 static flag -static works... yes checking if g++ -std=gnu++11 supports -c -o file.o... yes checking if g++ -std=gnu++11 supports -c -o file.o... (cached) yes checking whether the g++ -std=gnu++11 linker (/usr/bin/x86_64-linux-gnu-ld -m elf_x86_64) supports shared libraries... yes checking dynamic linker characteristics... (cached) GNU/Linux ld.so checking how to hardcode library paths into programs... immediate checking whether g++ -std=gnu++11 supports C++11 features by default... yes Looks like it. That of course breaks. Now the question is why autoconf unhelpfully adds that with gcc 16... CC'ing the autoconf maintainer. I see 2.72-6 removing debian/patches/fix-cxx-stdcxx-test.diff but according to the debdiff it was not applied before anyway... That might also be the explanation for a loads of other gcc 16 FTBFS....
