nested classes

[cronus]

Hi

How to I specify casts with nested classes, e.g. 
if I enter the debugger command 
print (A::AA *)a
I get the error message:
A parse error in expression, near ')a'

I am using ddd version 3.3.9, and gdb version 6.1-debian.

Thanks in advance

        public:
                int getB(void) { return _b;}
                void setB(int b) { _b = b; }
        private:
                int _b;

        public:

                                int getAA(void) {
