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.

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.

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.

Can't reproduce.

Thank you for this bug report. To properly diagnose the problem, we
need a short but complete example script to be able to reproduce
this bug ourselves. 

A proper reproducing script starts with ,
is max. 10-20 lines long and does not require any external 
resources such as databases, etc.

If possible, make the script source available online and provide
an URL to it here. Try to avoid embedding huge scripts into the report.

Description:

Making a simple xml transformation using xslt_process
gives from time to time a segfault. The  php code looks like this:

$xmlFile = "file.xml";
$xsl_url = "file.xsl";
$result = xslt_process($xh, $xmlFile, $xsl_url);
if ($result) {
echo $result;
} else {
echo "Error";
}
xslt_free($xh);

I provide hereafter a backtrace after the segfault occured:

Program received signal SIGPIPE, Broken pipe.
