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:
