The ddnet AUR package's check() run some tests, including on Rust code. Building in a clean chroot, the current version that once built just fine is now failing on Rust tests. Since I didn't change a single config in my system since the last successful build, I'm assuming this is related to a package upgrade that changed a flag or something.
Logs: ddnet-18.0.3-1-x86_64-build.log, ddnet-18.0.3-1-x86_64-check.log
Help please?
Here is one of the failure logs:

I was able to avoid the issue by disabling LTO. So I would suspect the issue was introduced on your system when you updated pacman that contained an updated /etc/makepkg.conf with LTO now enabled in the options array.
Edit:
Fixed static library build by adding -ffat-lto-objects to CXXFLAGS.

Indeed, /etc/makepkg.conf has options=(... lto) and LTOFLAGS="-flto=auto" since pacman 6.0.2-8, introduced in the pacman commit 90bf367e6. Thanks for debugging and suggesting this flag!
