#38134 [Fbk->Opn]: segfault while calling xslt_process

ID: 38134 User updated by: gerome dot fournier at infomaniak dot ch Reported By: gerome dot fournier at infomaniak dot ch -Status: Feedback +Status: Open Bug Type: XSLT related Operating System: Debian Sarge PHP Version: 4.4.2 New Comment: You can get the details about this server using the following URL: http://imu60.infomaniak.ch/phpinfo.php We're using sablotron version 1.0 as provided by Debian sarge, and the configure command line is the following: './configure' '--disable-all' '--prefix=/opt/php' '--with-apxs=/opt/apache/bin/apxs' '--disable-ipv6' '--with-pear' '--enable-xml' '--with-expat-dir=/usr' '--with-pcre-regex' '--enable-memory-limit' '--enable-ftp' '--with-mysql=/opt/misc/mysql' '--with-zlib-dir=/usr' '--with-openssl=/usr' '--with-zlib=/usr' '--enable-bcmath' '--enable-calendar' '--enable-ctype' '--with-curl=/usr' '--with-dom' '--with-dom-xslt' '--with-dom-exslt' '--enable-exif' '--with-gd' '--with-jpeg-dir' '--with-png-dir' '--with-xpm-dir' '--with-ttf' '--with-freetype-dir' '--enable-gd-native-ttf' '--with-gettext' '--with-iconv' '--with-imap' '--with-kerberos' '--with-imap-ssl' '--enable-mbstring' '--enable-mbregex' '--with-mcal=/usr' '--with-mcrypt' '--with-mhash' '--enable-overload' '--enable-posix' '--enable-session' '--enable-tokenizer' '--enable-wddx' '--enable-xml' '--enable-xslt' '--with-xslt-sablot=/usr' '--with-zip' '--with-pdflib=/opt/misc/pdflib' '--with-tiff-dir=/usr' '--with-ming=/opt/misc/ming' I don't have a more detailed GDB backtrace to provide for the moment. Previous Comments: ------------------------------------------------------------------------ [2006-08-17 10:01:09] tony2001@php.net What is the version of Sablotron used? Are you able to get a decent GDB backtrace (using PHP configured with --enable-debug)? What was your full configure line? It works just fine here with 1.0.1 & Linux i386. ------------------------------------------------------------------------ [2006-08-17 09:48:45] gabriel dot zerbib at protilab dot com I'm sorry Tony, you were a little bit quick in closing with "can't reproduce". You can just try the online demo. You'll manage to achieve the 100 iterations for some time, but if you hit Refresh a few times, you sure will run into the problem: the page will not come to you, your browser will report some proxy error or some "Host not found" error, which is in fact caused by a violent crash of the PHP script and PHP interpreter, never returning a response to your browser. Please do not close this bug report too fast, as sample data were properly provided, and the target platform and system and version. Thanks. ------------------------------------------------------------------------ [2006-08-17 09:43:05] tony2001@php.net Can't reproduce. ------------------------------------------------------------------------ [2006-08-17 09:42:11] gerome dot fournier at infomaniak dot ch Re-opened as the owner of the web site provided new feedbacks. ------------------------------------------------------------------------ [2006-08-17 09:22:12] gabriel dot zerbib at protilab dot com TEST DATA: The files can be found at: http://www.protilab.com/test/sample.xml http://www.protilab.com/test/sample.xsl And the PHP script can be run online at: http://www.protilab.com/test/sample.php SCENARIO: An XSLT processor is instanciated using the XML and XSL files specified in the arguments, in a loop of 100 iterations. Among these 100 iterations, a seg-fault is likely to happen. XML file to process (sample.xml): --------------------------------------------------- <?xml version="1.0" encoding="iso-8859-1"?> <?xml-stylesheet type="text/xsl" href="sample.xsl"?> <root> <node1 id="foo"> <subnodeA>Some Data A</subnodeA> <subnodeA attr="123">Some Mode Data A</subnodeA> </node1> <node1 id="bar"> <subnodeA>Some Data A in another node</subnodeA> <subnodeA attr="345">Some Mode Data in second node</subnodeA> </node1> </root> --------------------------------------------------- XSL file to apply (sample.xsl): --------------------------------------------------- <?xml version="1.0" encoding="iso-8859-1"?> <xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"> <xsl:template match="/"> <html> <head> <title>Title here</title> </head> <body> <xsl:for-each select="/root/node1"> <xsl:value-of select="@id"/> <ul> <xsl:for-each select="subnodeA"> <li><xsl:value-of select="text()"/> <xsl:if test="@attr"> ( <xsl:value-of select="@attr"/> ) </xsl:if> </li> </xsl:for-each> </ul> </xsl:for-each> </body> </html> </xsl:template> </xsl:stylesheet> --------------------------------------------------- PHP script (sample.php) --------------------------------------------------- <? $xmlFile = 'sample.xml'; $xsl_url = 'sample.xsl'; for($i = 0; $i < 100; ++$i) { $xh = xslt_create(); xslt_set_encoding($xh, 'iso-8859-1'); xslt_process($xh, $xmlFile, $xsl_url, 'result.html'); xslt_free($xh); echo("iteration: $i = OK <br/>\n"); } ?> --------------------------------------------------- ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
