Hi Steven.
the problem is that a channel access put fails at PINI time.
Processing the first record afterwards will cause the second record
to properly process, too.

Is think this is a feature, not a bug. A record should not be accessible
by channel access before it is initialized. Otherwise all clients could see the
uninitialized values of the records.
