The fix is near impossible with current implementation.
May be it could be fixed in future version of PHP with try/funally.
BTW, we decide not to include try/finally into PHP 5.1.

I'm not sure if we can qualify this as a bug actually. But atleast I
can offer an explanation. If you use @ the error reporting level will
be set to 0 before an expression (make_exception()) and set's it back
to the original value after it. Because the throwing of the exception
immediately jumps to the catch block, the error reporting level is not
reset back to it's old value. I'm not sure how easy this is to fix.

Description:
------------
If exception is throwed with error suppression (@) and catched by
try/catch block error_reporting will fall to 0

Reproduce code:
---------------
ini_set('display_errors', 1);
error_reporting(E_ALL | E_STRICT);

echo "1. error_reporting = " . error_reporting() . "\n";

function make_exception()
{
    throw new Exception();
}

try {
    @make_exception();
} catch (Exception $e) {}


echo "2. error_reporting = " . error_reporting() . "\n";

Expected result:
----------------
1. error_reporting = 4095
2. error_reporting = 4095


Actual result:
--------------
1. error_reporting = 4095
2. error_reporting = 0
