*
* Notice the inclusion of PEAR's DB class at the bottom. Make sure
* your include_path or the path in the require statement below is
* correct.
*
* The crashes involve a weird combination of factors. The factors
* can be rearranged to cause the crashes to vanish.
*
* If the parent class' name is 15 characters long, it crashes, but if
* it's 14 or 16 characters long, it does not. But the length of the
* class name isn't _really_ the problem.
*
* For example, the length of the method names and the existence of
* parameters play a role too. See the comment in the class for more
* details.

Description:
Using the latest snapshot, php5-win32-200311260330.zip, when a script
loads up a bunch of class files, a Dr Watson error dialog appears
saying PHP has crashed. Note, I'm just including the files, not
creating an object via new.
I've tried to pin this down to some particular lines of code, but have
been unable to find something in particular.
While certain combinations of my class files and PEAR::DB create the
crash, others don't.
This code worked fine until now, so I don't think it's the content. In
addition, I've tweaked PEAR.php and DB.php so methods that return by
reference are always returning variables.
Below is an excerpt from a dump file as examined by WinDbg:
(5e4.600): Access violation - code c005 (!!! second chance !!!)

ID: 26418 Updated by: [EMAIL PROTECTED] Reported By: danielc at analysisandsolutions dot com -Status: Open +Status: Feedback Bug Type: Zend Engine 2 problem Operating System: Windows 2000 PHP Version: 5CVS-2003-12-1 New Comment: 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 possible, make the script source available online and provide an URL to it here. Try avoid embedding huge scripts into the report.
