Win 32 'could not attach to proper memory at fixed address'

Running RC1 on Windows 2003 Server I get the following:

2004-12-13 13:01:11 FATAL: could not attach to proper memory at fixed address:
shmget(key=5432001, addr=00DB0000) failed: Invalid argument
2004-12-13 13:01:11 FATAL: could not attach to proper memory at fixed address:
shmget(key=5432001, addr=00DB0000) failed: Invalid argument
2004-12-13 13:01:11 LOG: background writer process (PID 3548) exited with exit
code 0
2004-12-13 13:01:11 LOG: terminating any other active server processes
2004-12-13 13:01:11 LOG: all server processes terminated; reinitializing

I noticed that there are a couple of references to this on the mailing list
however the 'Invalid argument' part of the message appears to be different.

The problem can be worked around (if you are running locally) by changing the
postgresql.conf from:
listen_addresses = '*'
to:
listen_addresses = '127.0.0.1'
