Now that I am looking at this, I see that the attname has four bytes of
NULL's before it.  This looks like some kind of alignment error,
perhaps, like the previous entry is writing past its end and into the
this one.  Everything after the 'data' element shows garbage because it
is all shifted over.  I did add the atttypmod field to the pg_attribute
structure, and it is an int2/short.  Wonder is that threw off some
alignment, and only Alpha has a problem with it.

Please try with Assert on:

    configure --enable-cassert

Man, if I introduced this problem somehow, I am going to be upset with
myself, and I am sure a few Alpha users will join me.
