Description:
------------
The first method I call on a soap client object works fine. The second call however, produces a segfault. When I recreate the soap client object in between the calls the script works fine. This bug also occurs in PHP 5.0.4 and 5.0.5. But it didn't exist on my previous i386 Debian woody server (the php code is identical).
Reproduce code:
---------------
$wq = new SoapClient('http://soap-server-ip/WQLogin/wsdl/IWQLoginService');
$ul = $wq->GetUserList();
foreach ($ul as $array) {
if($array->UserName == $_GET['username']) {
if($array->Password == $_GET['password']) {
if(in_array('1',$array->Permissions)) {
$wq->GetUserUID($array->UserID);
The last line causes the segfault. But when I insert: $wq = new SoapClient('http://soap-server-ip/WQLogin/wsdl/IWQLoginService');
one line before the last, it works fine.
Expected result:
----------------
no segfault ;)
Actual result:
--------------
segfault, haven't got a backtrace yet. Can create one if you require it.

Also it doesn't matter what the second soap request is. The second one just causes a segfault. In the simplest form: webserver:~# cat login.php #!/usr/local/php-5.1.1/bin/php <?php $wq = new SoapClient('http://soap-server-ip-address/WQLogin/wsdl/IWQLoginService'); $foo = $wq->GetUserList(); // Soap request 1 works fine $wq = new SoapClient('http://soap-server-ip-address/WQLogin/wsdl/IWQLoginService'); $bar = $wq->GetUserList(); // Soap request 2 causes segfault, but works fine after a reconnect ?> webserver:~# ./login.php webserver:~# vim login.php webserver:~# cat login.php #!/usr/local/php-5.1.1/bin/php <?php $wq = new SoapClient('http://soap-server-ip-address/WQLogin/wsdl/IWQLoginService'); $foo = $wq->GetUserList(); // Soap request 1 works fine $bar = $wq->GetUserList(); // Soap request 2 causes segfault, but works fine after a reconnect ?> webserver:~# ./login.php Segmentation fault (core dumped) webserver:~#I updated to the latest libxml2 (2.6.22) and recompiled php with this lib. And it still segfaults. Here is a backtrace from this version: #0 0x0000000000000000 in ?? () #1 0x0000000000000003 in ?? () #2 0x0000000000000000 in ?? () #3 0x0000000000000000 in ??
