Config options:

./configure \
        --with-mysql=/usr/local/mysql \
        --with-apache=/usr/local/src/apache \
        --with-gd=/usr/local/src/gd \
        --with-jpeg-dir=/usr/local/src/jpeg \
        --with-xml \
        --with-mhash=/usr/local/src/mhash \
        --enable-versioning

Sample script:

<?php

class Bug {
    function test() {
        $x = 5;
    }
}

$nl = new Bug();

$nl->
    test();

Header('Content-type: text/plain');

echo 'Hello.';
?>

Header() complains that output started on line 11, which is the "$nl->" line. On references to variables (instead of method calls) this would sometimes cause the parser to output an error.

Note, however, that:

$nl->[space]
    test();

and:

$nl
->test();

...do not have this problem.
