pg_shadow [1] Bus error (core dumped)

Hi List,

I've just tried to initdb on a new installation of 7.3.9 which resulted
in this output:

$ initdb -D /usr/local/pgsql/data
The files belonging to this database system will be owned by user
"postgres".
This user must also own the server process.

The database cluster will be initialized with locale C.

Fixing permissions on existing directory /usr/local/pgsql/data... ok

initializing pg_shadow... [1] Bus error (core dumped)
"${PGPATH}/postg...

initdb failed.

The installation is running on a 4 x 125MHz (Ross HyperSparc) SS20 with
512Mb RAM. PostgreSQL was compiled from source using GNU Make 3.80 using
the default configuration.

Can anyone help me out with this one?
