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.

Description:
------------
When running the sample code PHP 5.3 and PHP 5.3 latest snapshot crash
with Win32 exception.
It was reproducable on two different machines. But you need the MS
Access Jet Engine to work with this sample code (means you probably need
MS Access).
With php 5.2.10 it runs like expected - no exceptions, no errors.
Reproduce code:
---------------

Expected result:
----------------
nothing special here - just works with 5.2.10
Actual result:
--------------
Win32 exception crashes php.exe
