ID: 26286 Comment by: info at phpsydney dot com Reported By: igg10 at alu dot ua dot es Status: No Feedback Bug Type: Apache2 related Operating System: Windows 2000 PHP Version: 4.3.4 New Comment:
The error moves around. When I add code to pinpoint the error, the error moves because of the extra code. Here is some code and the output. The content of the array becomes corrupt. The foreach goes in to a loop because the array is corrupted after the start of the foreach loop. In the original code in my script, the array contained objects, the objects were corrupted, and then Apache blew up with the 3221225477 error. I replaced the objects with strings and the array still became corrupt, only the symptom changed. I think the 3221225477 error occurs when PHP's variable space becomes corrupt and the corruption damages an object. $attributes = array('name', 'type', 'value'); print('attributes: '); var_dump($attributes); print('<br>'); foreach($attributes as $attribute_key => $attribute_name) { print('At attribute: ' . $attribute_name . ' attributes: '); var_dump($attributes); print('<br>'); if(isset($this->_attribute[$attribute_name])) { unset($attributes[$attribute_key]); } } attributes: array(3) { [0]=> string(4) "name" [1]=> string(4) "type" [2]=> string(5) "value" } At attribute: name attributes: array(2) { [0]=> string(4) "name" [1]=> int(0) } At attribute: 0 attributes: array(2) { [0]=> int(0) [1]=> int(0) } At attribute: 0 attributes: array(2) { [0]=> int(0) [1]=> int(0) } At attribute: 0 attributes: array(2) { [0]=> int(0) [1]=> int(0) } At attribute: 0 attributes: array(2) { [0]=> int(0) [1]=> int(0) } Previous Comments: ------------------------------------------------------------------------ [2004-06-04 14:40:57] info at phpsydney dot dot dot net I updated to PHP 4.3.7. Same problem. Have latest Apache 2. I notice people reporting the same error message for modperl, ldap, imagemagick, and tomcat on both Apache 1 and Apache 2. Memory problem? No, I increased from 8 to 200 MB and still same problem in same time. I added var_dump everywhere to see what happens to the script variables. Just before the crash the variables are corrupted as if references were all broken. vardump shows variables within arrays as now containing arrays. Entries in arrays get & in front of them which are not there in earlier vardump. ------------------------------------------------------------------------ [2004-05-31 17:00:53] populus117 at hotmail dot com I discovered something that may have been the problem. Quite trivial and embbrasing though... I was testing all the different combinations between Apache 1.3.3, Apache 2.0.4, PHP 4.3.6 and PHP 5.0.0 RC2, and in the process of switching between PHP4 and PHP5, I found out that I did not copy the php5ts.dll to the system32 folder. I know that in the readme it says that the system searches the PHP folder as well for this file but once I put that file into system32, it *appears* to have solved the problem. I haven't seen the bug so far and hopefully I'm right =D Conclusion: Stupid mistakes are the hardest to realise and find. ------------------------------------------------------------------------ [2004-05-31 14:49:55] populus117 at hotmail dot com Getting exact same error. I'm using: Windows 2000 SP4 Apache 2.0.48 PHP5.0.0-RC2 I tried to trace the source of the problem but found it difficult, if not impossible as the error seems to occur randomly. Loading the same page with the same conditions doesn't seem to consistantly give me the error. The best reason I could think of right now is that there are too many loops in the page (I checked for infinite loops and found none). The pages that has this happen to it is mainly pages with databse queries, which takes a while since the database is remotely accessed. Would be nice if this was looked into and hopefully fixed soon. ------------------------------------------------------------------------ [2004-05-17 16:09:53] hakk at email dot it Apache: 2.0.49 (happens with apache 1.3.31 too) PHP: 5.0.0RC2 OS: Windows XP PRO SP1 The code below reproduces the crash on my machine. <? class my_error { private $_errors; private $_errorNumber; function __construct() { set_error_handler(array(&$this, 'handler'), E_ALL); $this->_errorNumber = 0; } function handler($errno, $errstr, $errfile, $errline, $errctx) { echo "ERROR= $errno<br> $errstr<br> $errfile<br> $errline<br> $errctx<br>"; echo $this->_errorNumber."<br>"; /* if you comment out the next 4 statements, everything works correctly */ $this->_errors[$this->_errorNumber]['errno'] = $errno; $this->_errors[$this->_errorNumber]['errstr'] = $errstr; $this->_errors[$this->_errorNumber]['errfile'] = $errfile; $this->_errors[$this->_errorNumber]['errline'] = $errline; $this->_errorNumber++; } } class my_class { function throw_exception($param1, $param2) { echo "$param1, $param2"; throw new Exception(); } } $err = new my_error; //if i dont use my own error handling class, everything works out try { $test = new my_class; call_user_func_array(array($test, "throw_exception"), array('a','b')); //makes apache crash //$test->throw_exception('a','b'); this works with no problems } catch(Exception $e) { echo $e; } ?> A few notes... If i dont use my error_class, everything works fine, and PHP gives me this warning "Warning: call_user_func_array() [function.call-user-func-array]: Unable to call my_class::throw_exception() in C:\Programmi\Apache Group\Apache2\htdocs\testfield\exception.php on line 40" problably since i threw an exception in that function. If i use my error_class and i dont use the call_user_func_array, but instead i call $test->throw_exception() everything works fine again (because no Warning is generated?) If i use my error class and call call_user_func_array then everything blows up and apache restarts giving "[Mon May 17 15:59:16 2004] [notice] Parent: child process exited with status 3221225477 -- Restarting." Hope this helps. ------------------------------------------------------------------------ [2004-05-04 09:25:24] gaida at gmxpro dot net Apache: Apache 2.0.49 (Win32) PHP : PHP 4.3.6 MySQL : MySQL 4.0.14-NT OS : Windows XP Pro SP1 Server crashes only (Parent: child process exited with status 3221225477 -- Restarting.) when Turck MMCache (version 2.4.6 for php 4.3.6) is enabled and JPGraph generated images were accessed.
