Thanks Bryan.  Yup their backtraces look just like mine.

I'll keep an eye on that bug, if somebody fixes it before I get a Round Tuit that'd be nice for me!  Otherwise I guess the patch goes upstream.

Have you checked upstream?
https://sourceware.org/git/?p=glibc.git;a=shortlog;h=refs/heads/master
