There's a KFAIL in the test-case, but that one triggers on f.i. output like
this:

Hmm, I've lost the ability to reproduce this.

I've build all commits in the range
58fd1204aa0f66dd2df30f673c9441e0265b8515..49c843e6d2d0577200e7c1d2d02855f21a3a9dde
and didn't manage to reproduce.

--- Comment #4 from Andrew Burgess <aburgess at redhat dot com> ---
I've also tried to reproduce this without success.  I did wonder if it was
possible that an update to libreadline might trigger this behaviour, with GDB
built against readline 8.1, then an update to readline 8.2 being performed
without rebuilding GDB.

It was in the 8.1 -> 8.2 readline update that the bugs related to how the
'quit' is printed were fixed.

That said, I don't have a solid story for what might be triggering the weird
behaviour - the readline update is just an idea.  I have an opensuse VM, but I
can't figure out how to downgrade readline to 8.1 in order to test the
theory...
