New Comment:
Well, I saw that the backtrace threw a problem regarding the XSL, well,
I'll paste the code but I use a transformation when throwing an
exception, so, I could show it passing an XML to an XSL. This is the
code:
Throws the Exception:
try{
throw new PHPDevException($this ->
error,100,"DAO",$part,false,"SQL","SQL DAO",$qry); }catch
(PHPDevException $ac){
$ac -> toScreen();
die();
}
The Exception class:
<?
//require_once("classes/DAO.inc.php");
//require_once("Config.inc.php");
require_once("XSLoader.inc.php");
/**
* @author Francisco A. Castillo Guerrero. This class handles
* all the exceptions created by the assessment center
* redesign.
*/
class PHPDevException extends Exception{
protected $code;
protected $message;
protected $title;
protected $fclass;
protected $method;
protected $line;
protected $sys;
protected $uri;
protected $sql;
protected $redire;
/**

*/
public function __construct($errmsg, $errcode, $class, $method,
$redire, $title = 'AC', $system = '', $sql = ''){
$this -> title = $title;
$this -> fclass = $class;
$this -> method = $method;

parent::__construct($errmsg,$errcode);
}
/**

$xsl -> importStyleSheet($doc);
$doc -> loadXML($xml);
return $xsl -> transformToXML($doc);
}
}
?>

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 <?php and ends with ?>,
is max. 10-20 lines long and does not require any external
resources such as databases, etc. If the script requires a
database to demonstrate the issue, please make sure it creates
all necessary tables, stored procedures etc.
Please avoid embedding huge scripts into the report.

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
http://bugs.php.net/bugs-generating-backtrace.php for *NIX and
http://bugs.php.net/bugs-generating-backtrace-win32.php 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.

Description:
------------
I'm running PHP 5.2.0 with Apache 2.2 under a Fedora Core 6 Platform
and when I throw a new exception, the server crashes and I prompts me
to download the file. I try to throw different exceptions, including
ADODB and it stills do the same.
I've checked the logs but the only thing that I see at the apache's one
is
[Fri Jan 05 08:52:34 2007] [notice] child pid 14712 exit signal
Segmentation fault (11)
Reproduce code:
---------------
try{
throw new PHPDevException($this ->
error,100,"DAO",$part,false,"SQL","SQL DAO",$qry);
}catch (PHPDevException $ac){
$ac -> toScreen();
die();
}
Expected result:
----------------
Show a screen with the Formatted Exception, Including the description
of the class that threw it.
Actual result:
--------------
The browser prompts me to download the file and save it
