Description:
------------
On the Constructor/Destructor page in the manual, the last note states that "Attempting to throw an exception from a destructor causes a fatal error." I've come into a scenario where I am able to throw an Exception, without fail, from a Destructor.

Below are just two examples, I'm sure there are more.

Reproduce code:
---------------
http://www.girsbrain.org/php_bugs/exception_deconstructor_01.phps
http://www.girsbrain.org/php_bugs/exception_deconstructor_02.phps

Expected result:
----------------
Fatal error: Exception thrown without a stack frame in Unknown on line 0

Actual result:
--------------
This should produce a Fatal error, but it doesn't

#0 \test.php(10): TestClass->__destruct()
#1 {main}

This is a documentation bug.

The "PHP Fatal error:  Exception thrown without a stack frame" is occurs only if exception thrown during PHP script shutdown, however objects that are destroied during script execution can throw exception from destructors without problem.

This bug has been fixed in the documentation's XML sources. Since the
online and downloadable versions of the documentation need some time
to get updated, we would like to ask you to be a bit patient.

Thank you for the report, and for helping us make our documentation better.

"Attempting to throw an exception from a destructor (called in the time of script termination) causes a fatal error."
