Looks like the code makes an incorrect assumption about pointer size and double variable size. You can use any of the x86_64 test machines, but I'm pretty sure you own a x86_64 machine yourself. You can build the package using fedpkg srpm mock -r fedora-rawhide-i386 cppad-20240000.1-1.fc40.src.rpm to reproduce this issue locally on either your or Fedora test machine. This is almost exactly what koji uses to build packages.
