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
