Operating system: Linux 2.6.18-gentoo
PHP version: 5.2.0RC5
PHP Bug Type: Scripting Engine problem
Bug description: Endless loop when for exception thrown on E_RECOVERABLE_ERROR
Description:
------------
When the error thrown by SWFMovie::save is catched by the error handler
and "converted" to an exceptions this results in an endless loop.
Tested with 5.2-RC5 and 5.2-RC6-dev.
I tested this with another E_RECOVERABLE_ERROR thrown by a wrong return
value of __toString, which does not cause the endless loop, so that it is
perhaps ming related.
Reproduce code:
---------------
<?php
function errorHandler($errno, $errstr, $errfile, $errline)
{
throw new Exception( 'An error occured.' );
}
set_error_handler( 'errorHandler' );
$movie = new SWFMovie();
$image = new SWFBitmap( file_get_contents(
'http://kore.phpugdo.de/jpg.jpeg' ) );
$object = $movie->add( $image );
$movie->save( 'test.swf' );
Expected result:
----------------
PHP Fatal error: Uncaught exception 'Exception' with message 'An error
occured.' in /path/file.php
Actual result:
--------------
Endless loop
Shortened backtrace after a SIGINT, which made me assume, that is a
problem in the scripting engine:
