#40609 [NEW]: Segfaults when using more than one SoapVar in a request

[robin dot harvey at chaptereight dot com]

From: robin dot harvey at chaptereight dot com
Operating system: Linux - Ubuntu
PHP version: 5.2.1
PHP Bug Type: SOAP related
Bug description: Segfaults when using more than one SoapVar in a request

Description:
------------
I've got a very simple soap service (written in Java/Tomcat/Axis) which
simply accepts and logs the XML of a soap request. I need to post complex
XML to the server (an XSL stylesheet) and I'm using SoapVar with XSD_ANYXML
and dealing with the XSL as a string in PHP. When I try to add more than
one SoapVar object encoded in this way, PHP segfaults. It's happy with 1
param as a SoapVar, and with both as simple strings.

Reproduce code:
---------------
<?php
$s = new
SoapClient('http://192.168.1.79:8080/axis2/services/BuddyTestService?wsdl');
$data1 = <<<XML
<meta>
<properties>
<of>the transform go here!</of>
</properties>
</meta>
XML;

$data2 = <<<XML
<more>
<nice>Random content</nice>
<being>sent to the soap server</being>
</more>
XML;

$tdata = new SoapVar($data1, XSD_ANYXML);
$t = new SoapVar($data2, XSD_ANYXML);

$data = array('TransformData' => $tdata, 'Transform' => $t);
//$data = array('TransformData' => 'foo', 'Transform' => 'bar');
$s->examine($data);
?>

Expected result:
----------------
NULL. The service is 'In only'

Actual result:
--------------

Hi,

I've uploaded the Soap service to an accessible site, and produced a
backtrace, as requested. I've not used dbg before, so please let me
know if i've done something wrong. I recompiled php with
--enable-debug: heres the configure line:
'./configure' \
'--with-apxs2=/usr/bin/apxs2' \
'--with-zlib' \
'--with-bz2' \
'--with-pdo-mysql' \
'--with-pdo-pgsql' \
'--with-xsl' \
'--with-pear' \
'--enable-soap' \
'--enable-ftp' \
'--with-gd' \
'--enable-mbstring' \
'--enable-sockets' \
'--with-mcrypt' \
'--enable-debug'

Here's a copy of the php script I'm using:
<?php
$xml1 = <<<XML
<this>
<might>be nice for a <while/> old chum</might>
</this>
XML;

$xml2 = <<<XML
<ok>
Run it through <dbg/> to see what's going on
</ok>
XML;

$c = new
SoapClient('http://bluelines.org:8080/axis2/services/StockQuoteService?wsdl');
$sv1 = new SoapVar($xml1, XSD_ANYXML);
$sv2 = new SoapVar($xml2, XSD_ANYXML);

$c->update(array('symbol' => $sv1, 'price' => $sv2));
?>

....and the dbg session, with a backtrace...

Thank you for this bug report. To properly diagnose the problem, we
need a backtrace to see what is happening behind the scenes. To
find out how to generate a backtrace, please read
[url]http://bugs.php.net/bugs-generating-backtrace.php[/url] for *NIX and
[url]http://bugs.php.net/bugs-generating-backtrace-win32.php[/url] for Win32

Once you have generated a backtrace, please submit it to this bug
report and change the status back to "Open". Thank you for helping
us make PHP better.

An accessible WSDL might also be helpful

Description:
------------
I've got a very simple soap service (written in Java/Tomcat/Axis) which
simply accepts and logs the XML of a soap request. I need to post
complex XML to the server (an XSL stylesheet) and I'm using SoapVar
with XSD_ANYXML and dealing with the XSL as a string in PHP. When I
try to add more than one SoapVar object encoded in this way, PHP
segfaults. It's happy with 1 param as a SoapVar, and with both as
simple strings.

Reproduce code:
---------------
<?php
$s = new
SoapClient('http://192.168.1.79:8080/axis2/services/BuddyTestService?wsdl');
$data1 = <<<XML
<meta>
<properties>
<of>the transform go here!</of>
</properties>
</meta>
XML;

$data2 = <<<XML
<more>
<nice>Random content</nice>
<being>sent to the soap server</being>
</more>
XML;

$tdata = new SoapVar($data1, XSD_ANYXML);
$t = new SoapVar($data2, XSD_ANYXML);

$data = array('TransformData' => $tdata, 'Transform' => $t);
//$data = array('TransformData' => 'foo', 'Transform' => 'bar');
$s->examine($data);
?>

Expected result:
----------------
NULL. The service is 'In only'

Actual result:
--------------
robin@robin-desktop:~/projects/buddy/tomcat/soap2$ php
test-client-joe.php
Segmentation fault (core dumped)

Hi,

I've uploaded the Soap service to an accessible site, and produced a
backtrace, as requested. I've not used dbg before, so please let me
know if i've done something wrong. I recompiled php with
--enable-debug: heres the configure line:
'./configure' \
'--with-apxs2=/usr/bin/apxs2' \
'--with-zlib' \
'--with-bz2' \
'--with-pdo-mysql' \
'--with-pdo-pgsql' \
'--with-xsl' \
'--with-pear' \
'--enable-soap' \
'--enable-ftp' \
'--with-gd' \
'--enable-mbstring' \
'--enable-sockets' \
'--with-mcrypt' \
'--enable-debug'

Here's a copy of the php script I'm using:
<?php
$xml1 = <<<XML
<this>
<might>be nice for a <while/> old chum</might>
</this>
XML;

$xml2 = <<<XML
<ok>
Run it through <dbg/> to see what's going on
</ok>
XML;

$c = new
SoapClient('http://bluelines.org:8080/axis2/services/StockQuoteService?wsdl');
$sv1 = new SoapVar($xml1, XSD_ANYXML);
$sv2 = new SoapVar($xml2, XSD_ANYXML);

$c->update(array('symbol' => $sv1, 'price' => $sv2));
?>

....and the dbg session, with a backtrace...
