But Xdebug won't show SplDoublyLinkedLists. Tried PHPStorm and Vdebug in Vim.

[3704398] <- property_get -i 14 -n "$stack->SplDoublyLinkedListdllist" -d 0
[3704398] -> <response xmlns="urn:debugger_protocol_v1" xmlns:xdebug="https://xdebug.org/dbgp/xdebug" command="property_get" transaction_id="14" status="break" reason="ok"><error code="300"><message><![CDATA[can
not get property]]></message></error></response>

Steps To Reproduce
  1. Run the attached xdebug_test.php, setting a breakpoint sometime after $stack->push
  2. Attempt to view the contents of $stack
  3. See "can not get property" response from Xdebug

Typo in description, sorry. Should be:
"Xdebug won't show SplDoublyLinkedLists. Tried PHPStorm and Vdebug in Vim."

This seems likely, as I've only covered certain SPL classes: https://github.com/xdebug/xdebug/blob/master/src/lib/var.c#L277-L311

Your phpinfo() says "Xdebug v2.9.2", so please upgrade to 3.0.2 first too, as Xdebug 2 is no longer supported

Sorry, that was the wrong php instance.
