Summary: Parse errors and segmentation fault when running initdb

System Configuration
--------------------
Operating System : SuSE Linux 5.3, kernel 2.0.35

PostgreSQL version : 6.4.2

Compiler used : gcc 2.7.2.1

Hardware:
---------
Linux MizarFive 2.0.35 #2 Sun Nov 29 22:13:38 MST 1998 i686 unknown

Versions of other tools:
------------------------
gmake 3.76.1
flex 2.5.4

--------------------------------------------------------------------------

Problem Description:
--------------------
When I run initdb, I get the following output:

initdb: using /slack/usr/local/src/postgres/pgsql/lib/local1_template1.bki.sourc
e as input to create the template database.
initdb: using /slack/usr/local/src/postgres/pgsql/lib/global1.bki.source as inpu
t to create the global classes.
initdb: using /slack/usr/local/src/postgres/pgsql/lib/pg_hba.conf.sample as the
host-based authentication control file.

We are initializing the database system with username postgres (uid=26).
This user will own all the files and must also own the server process.

Test Case:
----------
The only non-standard thing I did during compliation/installation was to change the install and source directories. For my postgres user, PGDATA=/slack/usr/local/src/postgres/pgsql/data and PGLIB=/slack/usr/local/src/postgres/pgsql/lib, and my source is in /usr/slack/local/src/postgres/postgresql-6.4.2.
I was following the directions directly from the INSTALL document, and I had reached the "Create the database installation" step.
