Strange "inaccessible value" in debugger

Question

Could anyone explain this screen:

As you can see I have simple array - debugger shows values of its elements when I use A[0], A1... but I cannot get elements with local variable A[i] (but value of "i" is shown correctly).

Project settings:
Debug info: ON
Local Symbols: ON
Optimization: OFF.

Project (one PAS file) is BUILD so DCU is fresh. You can see on that screen almost full code of this test project so there is no chance that array A or "i" is declared in some other unit etc...

Now I checked - the same code in Delphi XE3 works perfectly - debugger shows all values. It seems that XE4 has a serious bug in basic feature :-((

Answer 1

It doesn't work because 'val' is a function and not a variable. Double click on the watched item and check the property 'allow function calls'.

Answer 2

i is a var and this var need an amount for instance change i to 1 and check it;

A[1].val;
