My ISP recently upgraded from 4.0.3pl1 to 4.0.6 - i have a script that runs an 'array_unique' on a 2d array. This used to work previously, but now it reduces the array down to a single item.

Here is the section of script:
// CLEAN UP DUPLICATES THAT DON'T HAVE THE DESCRIPTION, BUT ARE THE SAME SECTION
                                if ( $debug ) echo "<P style='text-align:left'><B>CLEAN UP DUPLICATE SECTIONS</B><BR>
                                                                                                                <I>[\$idx,\$count]...</I><BR>";
                                $count = 0;
                                for ( $idx = 0; $idx < count($section_result); ++$idx ) {
                                        $comp1 = strtolower($section_result[$idx][0]);
                                        $comp2 = strtolower($section_result[$idx+1][0]);
                                        $comp3 = strtolower($section_result[$idx-1][0]);

                                        if ( $comp1 == $comp2 ) {
                                        // IF THIS ENTRY IS THE SAME SECTION AS THE NEXT ONE
                                                if ( $section_result[$idx+1][1] != '' ) {
                                                        $section[$count][0] = $section_result[$idx+1][0];
                                                        $section[$count][1] = $section_result[$idx+1][1];
                                                        ++$count;
                                                } elseif ( $section_result[$idx][1] != '' ) {
                                                        $section[$count][0] = $section_result[$idx][0];
                                                        $section[$count][1] = $section_result[$idx][1];
                                                        ++$count;
                                                }
                                        } elseif ( $comp1 != $comp3 ) {
                                                $section[$count][0] = $section_result[$idx][0];
                                                $section[$count][1] = $section_result[$idx][1];
                                                ++$count;
                                        }
                                        if ( $debug ) echo "[$idx,$count] " . $section[$count-1][0] . " -- " . $section[$count-1][1] . "<BR>";
                                } // close for

                                if ( $debug ) echo "</P>";

                                $section = array_unique($section);

                                if ( $debug ) {
                                        echo "<P style='text-align:left'><B>UNIQUE SECTIONS AFTER CLEAN-UP</B><BR>";
                                        echo "section count: " . count($section) . " | $count<BR>";
                                        echo "<I>Work it thru a 'for' loop:</I><BR>";
                                        for ( $idx = 0; $idx < $count; ++$idx ) {
                                                echo $section[$idx][0] . " -- " . $section[$idx][1] . "<BR>";
                                        }
                                        echo "<I>Work it thru a 'foreach' loop:</I><BR>";
                                        foreach ( $section as $message ) {
                                                echo $message[0] . " -- " . $message[1] . "<BR>";
                                        }
                                        echo "</P>";
                                        echo "<P style='text-align:left'><B>UNIQUE SECTION_RESULT AFTER CLEAN-UP</B><BR>";
                                        foreach ( $section_result as $message ) {
                                                echo $message[0] . " -- " . $message[1] . "<BR>";
                                        }
                                        echo "</P>";
                                }
