应用错误收集

我正在开发自己的PHP扩展，其中包含一个类。我最近从Ubuntu 9.04升级到9.10并且扩展了。我从尝试更新到10.04，看看它是否修复它，因为我的开发环境是10.04，它在那里工作正常。与我能理解的唯一主要区别是服务器是64位，我的笔记本电脑是32位架构。我有PHP版本5.3.2-1ubuntu4.5（Zend build 20090626）。

我试过运行我的测试PHP文件：

<?php
$server =  "http://localhost/";
$port = 1214;
$f = new PPKeyClient($server, $port);
var_dump($f);

        PPKeyClient_ce = zend_register_internal_class(&ce TSRMLS_CC);

        memcpy(&PPKeyClient_handlers, zend_get_std_object_handlers(), sizeof(zend_object_handlers));
        PPKeyClient_handlers.clone_obj = NULL;
        return SUCCESS;
}

        intern->last_curl_result = PPKC_NO_REQUEST;

        retval.handle = zend_objects_store_put(intern, PPKeyClient_object_dtor, NULL, NULL TSRMLS_CC);
        retval.handlers = &PPKeyClient_handlers;
        return retval;
}

PHP_METHOD(PPKeyClient, __construct)
{
        PPKeyClient_object *intern;
        char *url, *ssl_ca_crt = NULL;
        int port = 80, url_len, ssl_ca_crt_len = 0, ua_len = 0;

        if(zend_parse_parameters(ZEND_NUM_ARGS() TSRMLS_CC, "s|ls", &url, &url_len, &port, &ssl_ca_crt, &ssl_ca_crt_len) == SUCCES$
        {
                intern = (PPKeyClient_object*)zend_object_store_get_object(getThis() TSRMLS_CC);
//              intern->port = port;

//              intern->baseurl = estrndup(url, url_len);
//              intern->baseurl_len = url_len;
//              intern->ssl_ca_crt = estrndup(ssl_ca_crt, ssl_ca_crt_len);
//              intern->ssl_ca_crt_len = ssl_ca_crt_len;
//              intern->useragent = "PP KeyClient (PPExt#" PHP_PRIVATE_PASSWORDS_EXTNAME " v" PHP_PRIVATE_PASSWORDS_VERSION ")";
        }
}

我知道对intern = (PPKeyClient_object*)zend_object_store_get_object...行进行注释会使其工作，但显然我不能在没有它的情况下从构造函数中设置值。

我很迷茫，很感激任何帮助找到了什么！
