[avr-gcc-list] Problem with debbuggin with AVRStudio, WinAvr and JtagIce mkII

[antonioromano]

Hi,

I'm new here.
I'm working  with ATmega128, Stk500, stk501 and jTagIce mkII.
i have installed on my windows XP AvrStudio 4.12 and WinAvr 20050214.
WinAvr uses Avr-Gcc 3.4.3 and GDB 6.1. I have a problem with the following code:

#include <avr/io.h>

int somma(int a, int b)

{
                return a+b;
}

int main ()
{               int e = 10;             
                int r = 1;      
                r = somma(e,r);
                r=r+1;
                                return r;               
}

it's a stupid program. When debbugging it step by step the main regularly calls 
somma(e,r).
After somma(e,r) finished, the control flow does not return in main at r=r+1 
but in a part of memory without code  (after the exit() of the main). Can you 
help me with  this problem?

Best regards

Antonio
