On the note of overloading done by mbstring, it appears this behavior is not entirely stable. On at least one test system (Sun OS 5.9) it causes crashes and overruns by using the test script in the test suite. Ex: sapi/cli/php -d "mbstring.func_overload=1" -r '' Unknown(0) : Fatal error - (null)() [http://www.php.net/ref.mbstring]: mbstring couldn't find function mail. Could not startup.
