Log: Add a warning about the fatal error generated when you throw from __toString().
Prompted by bug #50699, although it doesn't really fix it as such.

@bjori The documentation does not say that __toString() must not throw an
exception. The fact is, this is currently an undocumented behaviour, that could
therefore be changed without causing much pain (we're supposed to write code
based on the documented behaviour of a function, not its side effects):
http://php.net/manual/en/language.oop5.magic.php#object.tostring
A feature request has been open, I would be grateful if you could give your
opinion there, especially now than PHP 5.5 is being developed:

Thank you.

Current behavior of __toString is crap. Why i can use trigger_error()
bug not throw Exception() in __toString()? Please fix it.

Description:
------------
Cannot throw Exceptions in __toString(). Instead it produces a Fatal
error.
Reproduce code:
---------------
<?php
class bar {
public function __toString() {
throw new Exception('Incomplete Data');
}
}
$foo = new bar();
echo $foo;
?>
Expected result:
----------------
Fatal error: Uncaught exception 'Exception' with message 'Incomplete
Data' in /-:6
Actual result:
--------------
Fatal error: Method bar::__toString() must not throw an exception in /-
on line 0
