    It took a lot of work, but I've created the definitive Linux distro flowchart (lemmy.world)

    Compiling everything with LTO landed me in a situation where a bunch of packages fail to build because apparently having some LTO'd static libraries can cause issues.

    I'm now going to start investigating where exactly the issue is. Trouble is, the package that was giving me errors, depended on a whole lot of static libraries, soooooo.... Good luck to me.

    Being an ultra-madlad, I used to also -ffast-math everything that didn't fail, but because I didn't know about package.env yet, I found it easier to just keep it off rather than turning it off and on again every time I needed to emerge something that failed because of it.

    Yeah, I think I've had that problem once or twice. I think I found the culprits by disabling all build flags for libraries that seemed related, rebuilding them, running emerge @preserved-rebuild and then repeating the process to narrow it down

    dmesg and PFL help with diagnosing crashes due to libraries, but I don't think that would help here

    If it helps, here's my package.env:

    # Build failures
app-emulation/wine-vanilla noflto O3
sys-apps/groff O3
dev-lang/rust noflto
dev-lang/python O3
sys-auth/polkit O3
sys-libs/libomp noflto
sys-libs/compiler-rt noflto
net-libs/nodejs O3
dev-lang/duktape O3
x11-drivers/xf86-video-intel noflto

# Runtime failures
gnome-extra/cjs noflto O3
sys-devel/llvm noflto
