I get a segfault if i want to pass an array with $object,'method' as second arg to xslt_set_error_handler.

the line looks like this:
xslt_set_error_handler($this->_parser, array($this,'xslt_trap_error') );

Hi,

could you verify if it works with current Sablot CVS version?
See:
http://www.gingerall.cz/charlie/ga/xml/p_sab.xml

for details on anoncvs access.

This version works for me, and is actually the same bug as #17791.

After installation of the Sablot-CVS my PHP (cli version) doesn't compile anymore. Tested with 4.2.1 and 4.3.0-dev ... 
Here's the error:
/usr/bin/ld: warning: libpng.so.2, needed by /usr/lib/libgd.so, may conflict with libpng.so.3

Ah, forgot some more
Just compiled it without cli and now i get the following error:

Starting web server: apache
Cannot load /usr/lib/apache/1.3/libphp4.so into server: /usr/lib/libsablot.so.0: undefined symbol: __vt_3ios
failed

Recently I downloaded Sablot 0.95 and the two patches ( One for sablot itself and one for PHP ( sablot.c ))

It's absolutely the same result. Nothing works.

ifstream should be in your stdc++ lib.
If you use:
LDFLAGS='-lstdc++' ./configure [your flags here]

does that help?

Here's what I get on my stdc++ lib:
$ nm /usr/lib/libstdc++.so | grep vt_3
00036238 D __vt_3ios

This bug has been fixed in CVS.

In case this was a PHP problem, snapshots of the sources are packaged
every three hours; this change will be in the next snapshot. You can
grab the snapshot at http://snaps.php.net/.
 
In case this was a documentation problem, the fix will show up soon at
http://www.php.net/manual/.

In case this was a PHP.net website problem, the change will show
up on the PHP.net site and on the mirror sites in short time.
 
Thank you for the report, and for helping us make PHP better.

It's fixed in the current version and there's a testcase for this as well: bug17931.phpt
