Summary0002114: Local variables are not shown on Return Value debug step

How to reproduce:

  1. Create the following code:
    namespace K;
    use Exception;

function myMethod($b)
echo "$b";
$f = new \stdClass();
$f->xx = [$b, new Exception()];
return $f; //place breakpoint here

$foo = 1;
$a = myMethod(42); //place breakpoint here

2. Start debugger
On the first breakpoint hit, the local variable `$foo` will be shown in Watches.
3. Press _Resume Program_, 
4. On breakpoint, press _Step Into_

There will be no local variable `$foo`.
TagsNo tags attached.

This is currently expected. In the inter-frame between return and the assignment of the return value, the function's stack and the variables that belong here have already been destroyed. I'm leaving this open to see if I can do something about it, but I can't guarantee that it is even possible.
