By the way, your report sounds like there's some kind of memory
corruption happening, so the problem is possibly something happening
before the call to htmlentities. It would be great if you could
reproduce this.

Thanks for your report.



However, I can't reproduce this with:



<?php

class A {

function __tostring() { return "aaa"; }

}



echo htmlspecialchars(new A());



Passing it to parameter 2, gives a message telling parameter 2 should be
long, object given.



There's nothing out of the ordinary with the implementation of
htmlentities/htmlspecialchars, so unless you have a way to reproduce
this, I'll close it as bogus in the next few days.

Description:
------------
When passing an instance of a class implementing __toString, as the
first argument 

to htmlentities or htmlspecialchars, the object is apparently not always
(maybe 

never?) cast to string before being pushed on the stack.

In some cases this will cause php to erronously output that the function
requires 

parameter 2 to be long, unknown given. This seems to be an error from
the 

underlying C function?

Sadly, I cannot provide a test script to reproduce the behaviour, but it
should be 

easy enough to check whether my theory is correct.
