我正在開發自己的PHP擴展，其中有一個類。我最近從Ubuntu 9.04升級到9.10，擴展功能破裂了。我自從嘗試更新到10.04，看看它是否修復它，因爲我的開發環境是10.04，它在那裏工作正常。從我能理解的唯一的主要區別是服務器是64位和我的筆記本電腦32位體系結構。我有PHP版本5.3.2-1ubuntu4.5（Zend build 20090626）。Segfault實例化類中的自定義PHP擴展C
我試圖運行我的測試PHP文件：
<?php $server = "http://localhost/"; $port = 1214; $f = new PPKeyClient($server, $port); var_dump($f);
在GDB：

而且從擴展相關位：
PHP_MINIT_FUNCTION(pp)
{
// Register PPKeyClient class
zend_class_entry ce;
INIT_CLASS_ENTRY(ce, "PPKeyClient", pp_functions);
PPKeyClient_ce = zend_register_internal_class(&ce TSRMLS_CC);
PPKeyClient_ce->create_object = PPKeyClient_object_new;
memcpy(&PPKeyClient_handlers, zend_get_std_object_handlers(), sizeof(zend_object_handlers));
PPKeyClient_handlers.clone_obj = NULL;
return SUCCESS;
}
zend_object_value PPKeyClient_object_new(zend_class_entry *ce TSRMLS_DC)
{
zend_object_value retval;
PPKeyClient_object *intern;
// TODO - only instantiate look at
// http://stackoverflow.com/questions/1906565/php-extension-library-accessing-php-superglobals
// or google for http://www.google.co.uk/search?hl=en&safe=off&q=superglobals+in+php+extensions&aq=f&aqi=&aql=&oq=&gs_rfai=
intern = ecalloc(1, sizeof(PPKeyClient_object));
zend_object_std_init(&(intern->std), ce TSRMLS_CC);
zend_hash_copy(intern->std.properties, &ce->default_properties, (copy_ctor_func_t) zval_add_ref, NULL, sizeof(zval *));
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，在註釋中intern = (PPKeyClient_object*)zend_object_store_get_object...行使它的工作，但顯然我不能設置從構造函數的值沒有臨時工噸。
我很失落，並會感謝任何幫助發現什麼！
