See: http://3v4l.org/9bcEJ Test script: --------------- interface TestInterface { public function foo(); } class Test implements TestInterface { public function foo(...$extraArgs) { } } $obj = new Test; $obj->foo(); Expected result: ---------------- Normal termination of script Actual result: -------------- Exit code 139, Segmentation fault ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=67938&edit=1
