Sorry, forgot to mention that - yes, I've removed the XSL calls, and
added a plain syntax error. The segfault still happens.

And does the problem occur without XSL (by causing some other error) ?
(I can't check the tar package right now)



[2007-10-22 11:35:37] per dot jessen at enidan dot com

My apache config is nothing particularly fancy, I just do plain
language negotiation. Still, I've updated the reproduce code:

http://jessen.ch/files/php-bug42666-oct2007.tar.gz



[2007-10-22 11:05:51] [EMAIL PROTECTED]

Cut'n'paste of the code needed:

?php
virtual(problem-include); // How?
if (FALSE===($xp=new XSLTProcessor())) die(unable to create xslt
engine);
$xsl=new DOMDocument;
$xsl-load(empty.xsl);
$xp-importStyleSheet($xsl);
?

I'm not sure how to use the files in that tar ball..I guess you have
some complex multiviews configuration also in there?
Can you please try to cut down all the external stuff to minimum, ie.
without using some fancy Apache configurations?

Does the crash happen if you have some other error? ie. without using
XSL?




[2007-10-01 12:25:27] per dot jessen at enidan dot com

Yes, I already did back on 14 September.  The tarball is the same:
http://jessen.ch/files/php-problem-sep2007.tar.gz



[2007-10-01 12:15:42] [EMAIL PROTECTED]

You need to provide us a short but complete example script which can be
used to reproduce this problem.

So you should be able to now provide the reproducing script here
instead of the tar package?

[2007-09-17 11:48:37] [EMAIL PROTECTED]

updated summary.
The xsl code just exposes the problem caused by the virtual call.



[2007-09-16 16:50:31] per dot jessen at enidan dot com

The reproduce script requires virtual() which isn't available in CLI.

OK, I've updated the tar ball:

http://jessen.ch/files/php-problem-sep2007.tar.gz

There are now only 5 lines of PHP code. The included file is empty as
is the XSLT stylesheet. I'm pretty certain the problem is actually
caused by the virtual() call, but it doesn't manifest itself till later.



[2007-09-14 09:55:01] [EMAIL PROTECTED]

Please cut the script down to minimum code (and without the HTML) that
can reproduce the error. Is this reproduceable running via CLI instead
of within apache? Also a backtrace would be useful as I cant reproduce
this in Linux or Windows.

Description:

Loading an XSLT stylesheet with a syntactical problem causes Apache to
segfault.  Looks like bad error-handling. 

Reproduce code:
---
http://jessen.ch/files/php-problem-sep2007.tar.gz

Let me know if you need a core dump or anything else. The above will
produce a segfault every time problem.phtml.en is loaded. 

Expected result:

Apache segfault.

is the XSLT stylesheet. I'm pretty certain the problem is actually
caused by the virtual() call, but it doesn't manifest itself till later.

Please cut the script down to minimum code (and without the HTML) that
can reproduce the error. Is this reproduceable running via CLI instead
of within apache? Also a backtrace would be useful as I cant reproduce
this in Linux or Windows.

Description:

Loading an XSLT stylesheet with a syntactical problem causes Apache to
segfault.  Looks like bad error-handling. 

Reproduce code:
---
http://jessen.ch/files/php-problem-sep2007.tar.gz

Let me know if you need a core dump or anything else. The above will
produce a segfault every time problem.phtml.en is loaded. 

Expected result:

Apache segfault.
