Bug description:  preg_grep changed behavior by design?

<?php

# The behavior of preg_grep() changed, seems to be broken.
# Don't know if it is a preg_grep() change or a Zend hash change.
# Indexing bug is my guess, or RedHat 7.0.
# Or maybe by design (see NEWS)
# Here is a test case for reproduction.

# Set up an array of strings.
$a = array( "foo", "bar", "baz" );

# Display them all first, FYI.
for( $bug = 0; $bug < count( $a ); $bug++ )
{
        echo "test: ".$a[$bug]."<br>";
}

# This works as expected, [0] is result, [1] is whatever.
$b = preg_grep( "/^foo/", $a );
echo "try to find foo as [0]: ".$b[0]."   count=".count( $b )."<br>";
echo "try to find foo as [1]: ".$b[1]."   count=".count( $b )."<br>";

# This fails as unexpected, [0] is whatever, [1] is result????
$b = preg_grep( "/^bar/", $a );
echo "try to find bar as [0]: ".$b[0]."   count=".count( $b )."<br>";
echo "try to find bar as [1]: ".$b[1]."   count=".count( $b )."<br>";

?>
