Did the distro apply a patch to glibc that broke things that others did not? Or did they pick up a newer version of glibc that other distros hadn’t? Yes, different distributions run on different versions of glibc. And different versions of glibc may have subtle differences in runtime behavior. That’s still ultimately a glibc back compost issue, not some kind of bug specific to glibc.
