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:
