OB is off. This is simple cli script, so everything goes to stderr. But there is another issue with zend_exception_error. It's not catchable. I checked ZE2 sources and error is triggered if exception is not an instance of EG(exception). I added debug messages and exception thrown is Exception instance, and the same is thrown in php code. I also tested code with valgrind and it shows no memory corruption or leaks. Maybe I should try similiar code with php-gtk2 which uses the same signals' emission feature? Piotras Thread at a glance:

I tested it with gtkwindow.php available in demos: Add simple test_cb class. class test_cb { function test_cba() { throw new Exception("DADA"); } } Connect to destroy signal in constructor: $this->connect_simple('destroy', array('test_cb', 'test_cba')); And try/catch : try{ new WindowTest(); } catch(Exception $e) { echo $e->getMessage(); } Output is: Fatal error: Uncaught exception 'Exception' with message 'DADA' I throw Exception and catch Exception.
