initdb - segmentation fault

Hello all,
I am trying to do an initdb and keep getting a segmentation fault
during the "Vacuuming database" portion of the initdb script.

I am running PostgreSQL 7.1.3 on RedHat 7.1. I have the following
rpm's installed:
postgresql-libs-7.1.3-1PGDG
postgresql-7.1.3-1PGDG
postgresql-server-7.1.3-1PGDG
postgresql-devel-7.1.3-1PGDG

Here is the output of the initdb -

[postgres(at)huma pgsql]$ initdb
This database system will be initialized with username "postgres".
This user will own all the data files and must also own the server
process.

NOTICE: Initializing database with en_US collation order.
This locale setting will prevent use of index optimization for
LIKE and regexp searches. If you are concerned about speed of
such queries, you may wish to set LC_COLLATE to "C" and
re-initdb. For more information see the Administrator's Guide.

Here is my postgres user .bash_profile -

[postgres(at)huma postgres]$ cat .bash_profile
# .bash_profile

# Get the aliases and functions
if [ -f ~/.bashrc ]; then
. ~/.bashrc
fi

[postgres(at)huma postgres]$

And here is the output from gdb on the core dumped by initdb... this
core was dumped in the $PGDATA/base/1 directory -

[postgres(at)huma pgsql]$ cat gdb.out

If anyone can help me out and let me know what is going, I would greatly
appreciate it as a major project depends on the completion on this dbase
installation. Thanks in advance,
