Description:
------------
PHP crashes sometimes, when first parameter of strcspn is empty (string with length zero).

Example: see http://bugs.typo3.org/view.php?id=4678

Maybe this bug is related to bug #39032 (strcspn stops on null character)?

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.

I am very sorry, I cannot extract the code that reproduces the crash. It only happens in the context of TYPO3 (see http://bugs.typo3.org/view.php?id=4678).

Using TYPO3, editing a "tt_news" Plugin results in an empty page. Tracing the error, the strcspn statement crashes. Extracting the block of code and executing it with the same parameters, everything works fine.

We cannot fix something we can't reproduce, sorry.
