As the title says I can't build fractal as it takes up all memory/swap and then get OOM killed. About the build environment as that might have some clues using mold and slibtool, compiling fractal with lto/nolto/clang/gcc nothing changes still OOMs. glib is built with static-libs USE and with clang, all rust dependencies of fractal are built with this package.env including trying to build fractal with it: COLOURS="-fdiagnostics-color=always -fcolor-diagnostics" COMMON_FLAGS="-march=native
