Can we try a simple -O rather than just -O2 and -O0.  Could this be some
type of optimizer bug in gcc2/Solaris?

Everything is pointing to indexing.c, from both the initdb failure and
the create function failure.  But I can't see anything wrong in there,
and other platforms seem to be OK.

Someone mentioned that Solaris does not use -O2 by default, and there
may be a good reason for this.

The new code is more streamlined from the megapatch, and perhaps the
optimizer is now able to do too much optimizing.

I don't want to go casting blame other places, but I think gcc that may
be the cause, and if it is, we just need to lower the default
optimization for those platforms.

Let's try adding Assert checking with the configure --enable-cassert
option, and compiling with -O rather than -O2 and see what happens.
