pgsql 7.0.2 initdb on alpha linux 2.2.15

Hi

I've successfully installed postgresql-7.0.2 from the sources on an Alpha
machine running Linux 2.2.15 with 128 MB memory, but `initdb` is failing:

postgres@viagra:/usr/local/pgsql$ /usr/local/pgsql/bin/initdb -D /usr/local/pgsql/data
This database system will be initialized with username "postgres".
This user will own all the data files and must also own the server
process.

Fixing permissions on pre-existing data directory /usr/local/pgsql/data
Creating database system directory /usr/local/pgsql/data/base
Creating database XLOG directory /usr/local/pgsql/data/pg_xlog
Creating template database in /usr/local/pgsql/data/base/template1

FATAL: s_lock(20323d40) at spin.c:116, stuck spinlock. Aborting.

FATAL: s_lock(20323d40) at spin.c:116, stuck spinlock. Aborting.

initdb failed.
Removing /usr/local/pgsql/data.
Removing temp file /tmp/initdb.10203.

This was compiled using unpatched source and I am a bit stumped, as it
were...

Thanks for any help.
