I tried it on master with opcache and it also worked fine. Can you provide more information about your environment? ------------------------------------------------------------------------ [2021-12-04 22:23:52] richiruizmartinez at gmail dot com getType()->__toString() also crashes: $foo = new stdClass; $foo->bar = 1; var_dump((new ReflectionObject($foo))->getProperties()[0]->getType()->__toString()); ------------------------------------------------------------------------ [2021-12-04 17:55:06] richiruizmartinez at gmail dot com Description: ------------ When I run the code shown below, PHP generates a segmentation fault.
