 New Comment:

I just downtracked the same problem. Additionally I have noticed that
after the fatal error occours (after throwing the notice, which is
swallowed), the shutdownFunction isn't called at all (tested on PHP
5.3.2).

When not throwing an error in error-handler, shutdownFunction is called
properly.

Description:
------------
Exception thrown in error_handler is swallowed if fatal error occurs
after error in same instruction



somewhat related (closed) bugs:

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
