Bash Version: 3.2
Patch Level: 25
Release Status: release

Description:
        read silently fails when stdin is piped to it.  -u switch does not help.
    Redirection works fine.

Repeat-By:
    echo 'one line' > /tmp/1line
    cat /tmp/1line | read
    does not set $REPLY, but
    read < /tmp/1line
    does.
