This is why running “gcc” gives you the upstream defaults, and not the flags we use to compile Fedora packages. For consistency, Ruby (and other compilation support tools) follow this pattern: Use distribution flags when building for Fedora, but use upstream flags when the user compiles packages (i.e., what Ruby uses, probably something involving -O2). > > Our build flags are fully ABI-compatible with each other, so mismatches will not cause any problems at the C/C++/ABI level. The question is why Ruby does this and how we can avoid this behavior. We could force installation of redhat-rpm-config package, providing the "/usr/lib/rpm/redhat/redhat-hardened-cc1", to every ruby user, but that does not seems right. There are also other similar issues discussing this situation [4], [5]. Any thoughts?
