public function plop() {
throw new Exception;
}
}

This code is much simplier IMO and demonstrates the same behaviour (both with 5.0.x & 5.1.x): <? class C { public function __construct() { $this->byePHP($this->plip()); } public function byePHP($plop) { echo "www.haricow.org"; } public function plip() { try { $this->plap($this->plop()); } catch(Exception $e) { } } public function plap($a) { } public function plop() { throw new Exception; } } new C; ?>Same bug, different code. two hours lost :( The constructor contains a return statement, but it is only <?php class UserModuleTest { public function __construct($obj) { try { new UserModuleTest($this->query()); } catch(Exception $e) { } } public function query() { throw new Exception; } } $test = new UserModuleTest(new UserModuleTest()); ?>Program received signal SIGSEGV, Segmentation fault.
