Description:
------------
This is fairly odd. Randomly PHP 5 will throw and
SQLiteException in code which does not use sqlite code 
at all, nor, as reported in the example below, uses $var 
(and this server is not running with E_STRICT error 
reporting).

sample error:

Fatal error: Uncaught exception 'SQLiteException' with 
message 'var: Deprecated. Please use the public/private/
protected modifiers' in /usr/college/home/
public_html/tickets.php:3 Stack trace: #0 {main} thrown 
in /usr/college/home/public_html/tickets.php on 
line 3

This type of fatal error "Uncaught exception 
'SQLiteException' " appears randomly so it is really 
hard to reproduce. It has no ties with the code or the 
line where the uncaught exception occurrs.

Okay, I found a way to reproduce this behavior.

In one of your browsers tabs please load
http://www.dotgeek.org/php5crash/DBCsample.php
for a couple of times or more.

on another tab load this page
http://dotgeek.org/forums/ which uses PHP 4 code (working fine on PHP5 under non E_STRICT setting). 

Now, if you load for a while both pages, first and second (sorry it might sounds crazy, but as a random bug, it is kinda hard to reproduce) you will see the PHP 4 code page (this happens with PHP5 code too but somehow was easier to reproduce with a PHP 4 code) crashing as per this image
http://www.dotgeek.org/php5crash/bug.jpg

note that the files on /forums/  do not use Sqlite but the page dies for an uncaught SqliteException. 

Once the crash occurs, it will appear randomly on several different pages, the only similarity is the stacktrace #0.

Let me know if I can be of any further assistance.

In response to the screenshot I just posted, common.php:120 is the following:

include($phpbb_root_path . 'includes/template.'.$phpEx);

David mentioned this on irc, so I felt I needed to try it immediately on my local installation: Windows XP Home running php5.01 as an Apache2 (2.0.49) module.

What is needed to duplicate this is a simple php and a sqlite database. I have zipped them and they are available here:

Here's a screenshot of the output:

It seems to be limited to when the secondary page contains code that is not E_STRICT compliant, as noted already. Indeed it seems that a class declaration is required (this was tested).

This bug has been fixed in CVS.

Snapshots of the sources are packaged every three hours; this change
will be in the next snapshot. You can grab the snapshot at

Thank you for the report, and for helping us make PHP better.

Fixed in PHP_5_0 and HEAD.
