It seems that count($this) doesn't check recursion. I think that count($this) should check if it is called inside of $this->count(), and if so, should ignore the Countable interface and just count the properties. Use case: if your object got special properties that you do not want to count, you can use something liek that: "function count() {return count($this) - numberOfSpecialProperties;}" Test script: --------------- class A implements Countable {function count() {return count($this);}} count(new A); Expected result: ---------------- 0 Actual result: -------------- Segmentation fault. ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=65867&edit=1
