Description:
------------
The test script will result in an "PHP Fatal error:  Uncaught exception 
'Exception'" with output of :
Start

Commenting out the if block will result in the expected output of :
Start
Inside
Finish

It seems the empty if block is nullifying the catch blocks.

Test script:
---------------
<?php
echo "Start\n";

try {
    try {
        throw new Exception("I'm dead");
        if (0) {
        }
    } catch (Exception $e) {
        echo "Inside\n";
    }
} catch (Exception $e) {
    echo "Outside\n";
}

echo "Finish\n";

Expected result:
----------------
Start
Inside
Finish

Actual result:
--------------
Start
PHP Fatal error:  Uncaught exception 'Exception'

I can't reproduce this issue. Are you using any Zend extension?

I have verified this behavior on two boxes.  The phpinfo are :
http://dl.dropbox.com/u/750344/mf-phpinfo.html
http://dl.dropbox.com/u/750344/dr-phpinfo.html

One has xdebug and eAccelerator and the other has just eAccelerator.  I'll create 
a VM without eAccelerator and attempt this again.  If the behavior doesn't 
continue, I'll submit the but to them.

I've got the same problem on PHP 5.3.6 and also using eaccelerator 0.9.6.

This is a known bug of eaccelerator's optimizer. To currently solve the problem, 
disable it :

eaccelerator.optimizer="0"

I suppose that the bug can be closed.

Sorry, but your problem does not imply a bug in PHP itself.  For a
list of more appropriate places to ask for help using PHP, please
visit http://www.php.net/support.php as this bug system is not the
appropriate forum for asking support questions.  Due to the volume
of reports we can not explain in detail here why your report is not
a bug.  The support channels will be able to provide an explanation
for you.

Thank you for your interest in PHP.
