Summary: Wrong compiling of for-statement

Initial Comment:
I am a beginner with WinAVR but in my opinion i 
detected a major compiler bug: Version is 3.4.1.

Following situation

typedef struct 
{
   unsigned char element1;
   unsigned char element2;
   unsigned char element3;
} SR1_Type;


SR1_Type var1;



function C_calculate()
{
   char * P_var1;

   unsigned int sum=0;

for (P_var1=&var1.element1; P_var1++; 
P_avr1<&var1.element3)
{
   sum+=*P_var1;
}

the programm did not work. I had a look to the 
Assembler and i detected that it is wrong(unfortunately 
if have it not with me)

i modified the program to a while construction and it 
worked pretty fine
