Rui, didn't you just apply a patch that "fixes" this since it can't be
set per-directory anymore?

Oops, my mistake. David's patch DOES solve the issue. (I just forgot to
rebuild the module :)

David, unfortunately your patch doesn't seem to solve the problem.

Furthermore, on my system, strlen never seems to be overridden
(mb_orig_strlen never exists) while substr always remains overridden
(mb_orig_substr always exists).

Are you sure this shutdown sequence is even being run?

Once the patch is applied this notice can probably be removed from 
the documentation.

Hi,

this patch fixes the problem (didn't find a way to attach a patch 
here):
http://www.dfoerster.de/misc/php-27421.diff

The problem was that the while loop in PHP_RSHUTDOWN_FUNCTION would 
terminate on the first function that was not overloaded. With a 
settin of 2, the str* functions would never be restored, because the 
mail function was not overloaded.

The patch changes the behaviour to be similar to the loop in 
PHP_RINIT_FUNCTION.
