Description:
If enabling shared memory on Windows 2003 Server x64 (64 bit) and using the MySQL Enterprise 5.0.30 binary, attempting to connect via the regular command-line client fails.

This seems to be a library bug that also causes problems for the GUI tools.

How to repeat:
1. Start MySQL with --shared-memory --shared-memory-base-name=MYSQL
2. Attempt to connect shell> mysql -u root 
3. Observe "Lost connection to server during query." error from command-line client.

The connection seems to succeed if '-h 127.0.0.1' is also specified. 

I suspect this problem has something to do with the default connection method attempted by the client library for 'localhost'.

Suggested fix:
unsure.

For Windows 64-bit builds, enabling shared-memory support caused
client connections to fail.
