Description:
------------

Test script:
---------------
function error($code, $message, $file = null, $line = 0) {
	echo "convert error to exception<br>\n";
	throw new \ErrorException($message, $code, null, $file, $line);
}

function shutdown() {
	echo "shutdown function called<br>\n";
}

set_error_handler('error');
register_shutdown_function('shutdown');

try {
	echo $crypto->compress();
} catch (\Exception $e) {
	echo "exception catched<br>\n";
}

echo "after fatal error<br>\n";

Expected result:
----------------
exception should be catched as in (note the @ operator to suppress a FATAL ERROR!):

function error($code, $message, $file = null, $line = 0) {
	echo "convert error to exception<br>\n";
	throw new \ErrorException($message, $code, null, $file, $line);
}

function shutdown() {
	echo "shutdown function called<br>\n";
}

set_error_handler('error');
register_shutdown_function('shutdown');

try {
	echo @$crypto->compress();
} catch (\Exception $e) {
	echo "exception catched<br>\n";
}

echo "after fatal error<br>\n";

Actual result:
--------------
1. Exception thrown in error_handler is swallowed
2. the "fatal error" after "Undefined variable" occurs
