The severity of this report will be raised before the forky release. The full build log can be found at: https://people.debian.org/~ema/gcc-16-rebuilds/output-1/ferret-vis_arm64.build.xz The last lines of the build log are at the end of this report. To build with GCC 16, either set CC=gcc-16 CXX=g++-16 explicitly, or install the gcc, g++, gfortran, ... packages from experimental. apt-get -t=experimental install g++ Common build failures include unused (but set) variables, array subscripts partly outside array bounds, and new/dropped symbols in Debian symbols files. For other C/C++ related build failures see the porting guide at http://gcc.gnu.org/gcc-16/porting_to.html Please only close this issue after double-checking that the package can be built correctly with GCC 16. Please do not reassign this bug to another package. If a fix in another package is required, then file a bug for the other package (or clone), and mark this bug as blocked by the bug in the other package.
