PHP新的SoapClient导致Apache崩溃

Question

我正在尝试在PHP中设置SoapClient，但它一直在崩溃Apache

这是我的PHP：

try{
    $o_soap = @new \SoapClient(
        "local/path/to/my/wsdl.xml",
        array(
            'exceptions' => true
        )
    );
    var_dump($o_soap->__getFunctions());
}
catch(SoapFault $e){
    die($e->faultstring);
}

这是Apache Log：

已在https://www.wsdl-analyzer.com上检查了WSDL并且没有返回任何错误。

更新

看起来它来自WSDL ......我尝试了另一个（较小的）并得到了预期的结果......

更新2

使用nusoap库解决
