Bug #66167 [NEW]: Incorrect result on list()

From: sander at prezent dot nl Operating system: Debian PHP version: 5.4.22 Package: Unknown/Other Function Bug Type: Bug Bug description:Incorrect result on list() Description: ------------ The attached test script seems not to work in PHP 5.4 and PHP 5.5: On PHP 5.3 the output is (as I expect): array(2) { [0]=> string(3) "foo" [1]=> string(3) "bar" } string(3) "foo" string(3) "bar" On PHP 5.4 the output is (which is IMHO incorrect): array(2) { [0] => string(3) "foo" [1] => string(3) "bar" } NULL NULL On PHP 5.5 the test code causes a SEGFAULT.
