That sounds like *so* much fun ;-)

OK, I've been ignoring the problem until now, and of course may not be
of any help even if I were trying to help. I'm also not quite up on the
history and sequence of events which led to our current state, and I'm
not sure we have a strong regression history yet to pin this down.

At the moment we have Bruce and the two sparc guys working on it, and
Bruce can't reproduce the problems on his machine and Keith's machine is
so dog-slow that he can't do much testing which involve full rebuilds.
Boy, it hasn't been long since that model Sparc was the best thing
going, eh?

Does anyone else have a machine (Linux x86, for example) which exhibits
problems with the current development tree, and who has an interest in
helping to track this down?

I hate to step away from docs, but could for a while if that would be
helpful. I've got a fairly fast machine and can try pinning down when
the problems started by doing full builds on fresh trees. Or since we've
been making steady incremental improvements to the tree, maybe we should
focus on a particular problem; my "can't create another index in the
current session" problem is probably related to whatever else is going
on with indices.

In general the problems persist across different "-O" compiler settings
and across different architectures and compilers, though with different
symptoms, so I would think that this is not a compiler bug per se.
