We had a recent report of a segfault on a Redhat compatible system, that seemed like it might originate from within its glibc [1]. Although all the versions there didn't match what you have, it's worth considering as a possibility. Maybe you can't install debuginfo packages because you don't yet have the necessary debuginfo repos set up. Just a guess. That is sometimes a required extra step.
