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.

The issue is still present at snapshot 5.3.2-dev, in both VC9 and VC6 thread safe versions. However, the issue does not present itself in 5.2.10.

I'm afraid I am unable to provide a smaller snippet of code than that given, as I don't know exactly where the error is within the code that causes the Application Error.

Little tip:
- remove all html
- try to remove part of the script to see if it still crashes
- post again the smallest script you can produce

It could be due to MySql but then you would only need mysql functions in your script.
