We also have a Fedora GDB bug report (and a bunch of dups) for this
problem:

  https://bugzilla.redhat.com/show_bug.cgi?id=1560010
  https://bugzilla.redhat.com/show_bug.cgi?id=1638798

I've been following Keith's efforts to fix this for a while now, and I
agree it's a good idea to include this one as a blocker for the 8.2.1
release.

Thanks,
