Source: fcl Version: 0.5.0-4 Severity: grave CMakeLists.txt sets -march=native in amd64 builds.
This means the code will only run on machines with a CPU compatible with the one on the machine where the package was built. Building on a different buildd machine can also change where the code can run - including breaking existing setups in stable updates. Please remove -march=native from CMakeLists.txt
