uVision Watch window does not like static ...

I use uVision 4.53 (with Armcc V4.1.0.894), processor STM32F407 with standard settings.

If I compile the following small program:

class Test{
public:
        static int i1;
        static int i2;

        int TestFunc( void);
};

int Test::TestFunc( void){
        i1= i2;
        return 0;
}

Test T;

int main( void){

        T.TestFunc();

        while( 1);
}

Then the watch window will show the class element T with the address "0x20000014 &T". This is a bit strange, as the address of i1 is 0x2000001C and address of i2 is 0x20000018 (as you can easily see if you look at the disassembly of the line "i1=i2" in function TestFunc).

If I try to change the value of T1.i1 in the watch window, it will fail - it always keeps zero, even after I enter some changed value.

The miracle happens, if I change the class definition to

class Test{
public:
        static int i1;
        static int i2;

        static int TestFunc( void);
};

Then the watch window will show the class element T with the address "0x00000000" (this usually would mean, that T is not used in the software - so this evidently is wrong). But nicely now i1 and i2 can be accessed without problems through the watch window.

I came to this problem through large classes with structs. For structs you clearly see the address in the watch window. There I recognized that the adresses sometimes were complete nonsense (it showed 0x4000000 adresses for normal variables - 0x4000000 is reserved for peripheral registers, so it is impossible).

It seems to be important, that all functions which are invoked from some static C-like funktion (as main()), need to be static. Otherwise the watch window does very strange things.

BTW: It would make a bit sense, if in the "Type" field uVision would show "class T" (now it says "struct T", which is slightly disturbing ...).
