Hi, Thanks for the report. Although I found a bug in the overloading code, I wonder why the mail() function entry was not found on RINIT. Any insights?

If sendmail binary cannot be found at configure time, mail() may not be compiled in PHP under UNIX like OS :( IMO, we should always compile mail() function. Distributors sometimes release PHP packages (i.e. RPM) w/o mail() sometimes. -- Yasuo Ohgaki

At the PHP Conference in Germany several of us have discussed the current state of mbstring and there was a proposal to not have it enabled by default for 4.3.0 release. It seems that the extension attempts to do "magic" stuff by overloading functions in the executor globals and, as Thies said, that could be dangerous. Also, doesn't it affect run-tests.php script currently?

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.
