call_user_func segfault

Hello, I've been running into a strange segfault with PHP 5.2.x (it works in PHP 5.3) when using call_user_func() recursively. I can not find out what causes it, but I did manage to have a simple test case. For the test to crash, you either need a debug build of PHP, or valgrind + USE_ZEND_ALLOC=0. You need run the script from within the "test" directory as it assumes file system layout. There is luckily a simple work around for the bug, by replacing: call_user_func( $callback, $callbackContext, $sourceDir, $entry, 42 ); with call_user_func_array( $callback, array( $callbackContext, $sourceDir, $entry, 42 ) ); I uploaded the test case as a .tar archive to http://files.derickrethans.nl/test.tar.gz It'd be ace if you could have a look at it (before I file a bug report). regards, Derick -- HEAD before 5_3!: http://tinyurl.com/6d2esb http://derickrethans.nl | http://ezcomponents.org | http://xdebug.org
