I finally figured out that the only way to fix this was to change the
specification so that a subpattern containing a back reference to itself is
always treated as an atomic group. This is similar to what happens to a
recursive or subroutine group call. I think this change will be OK, because the
previous state would always suffer from this bug, so I hope nobody will have
been relying on it.

I have committed a patch for this bug, and I have also released a second
release candidate for 8.01. You were just in time to catch this. If all goes
well, 8.01 will be out next week.
