Dunno for PHP 5 -- I have to make some tests before trying 
to switch -- but I wonder if this bug could be related to 
http://bugs.php.net/bug.php?id=37932.

PHP5 produces the same effects for you ?

Reclassified as Apache-related issue.

I forgot to mention that mbstring.func_overload is enabled  
on a per-vhost basis for some other web sites I'm hosting 
on this platform.

Agreed but I'm not making things up, you know. Something is 
obviously wrong on my Apache 1.3.34 setup. Could this be a 
conflict with some extension or Apache module? Of course, 
no opcode cache is running. Any tip welcome.

This weird behavior has been plaguing me for 2 months now 
and rebuilding PHP doesn't seem to help. I wrote a second 
test case which demonstrates that function overloading is 
effectively taking place sporadically while running under 
apache SAPI -- strlen() may accept the optional encoding 
argument (!?) as shown in the script output below.

If I do run the same script through PHP CLI or FastCGI, I 
get the following expected warnings:

PHP Warning:  Wrong parameter count for strlen() in 
/path/to/htdocs/bugs/mbinfo2.php on line 17
PHP Warning:  Wrong parameter count for strlen() in 
/path/to/htdocs/bugs/mbinfo2.php on line 25
