<?php

trait TBroken1 {
    public abstract function foo($a, $b = 0);
}

trait TBroken2 {
    public abstract function foo($a);

    public function foo($a) {
        echo 'FOO';
    }
}

$o = new CBroken;
$o->foo(1);

Fatal error: Declaration of CBroken::foo($a) must be compatible with TBroken1::foo($a, $b = 0) in %s on line %d
