Summary: Exception not properly caught when opcache enabled
Status: Open
Type: Bug
Package: opcache
Operating System: Linux
PHP Version: 5.5.3
Block user comment: N
Private report: N
New Comment:
Running with -d opcache.optimization_level=0xfffffffd shows the correct
behaviour.
That flag is the equivalent to turning on all optimizations except:
'ZEND_OPTIMIZER_PASS_2' /* Constant conversion and jumps */

This is an optimizer bug.
If you run with opcache.optimization_level=0 , the bug disappears.
I guess the bug is in the optimizer pass that handles ZEND_CATCH.
PS : I reproduced with a 5.4 base.

Description:
------------
When running the following script with opcache enabled, the exception is not
caught by the correct catch block. The exception should be caught by the
'caught by 1' block, but it is instead caught by the 'caught by 2' block.
Disabling opcache causes the exception to be caught in the correct block.
Run the script with:
php -n -d zend_extension=opcache.so -d opcache.enable_cli=1 script.php
Test script:
---------------
<?php
try
{
switch (1)
{
case 0:
try
{
}
catch (Exception $e)
{
}
break;
case 1:
try
{
throw new Exception('aaa');
}
catch (Exception $e)
{
echo 'caught by 1';
exit;
}
break;
}
}
catch (Exception $e)
{
echo 'caught by 2';
exit;
}
Expected result:
----------------
caught by 1
Actual result:
--------------
caught by 2
