Issue with debugging information generated by compiler gcc 4.3.3.

[sumanth <sumanth.gundapneni@xxxxxxxxxxxxxxxxxx>]

HI,
    I have an issue related to debugging information generated by compiler.
    DEBUGGING TYPE is DWARF2.
    COMPILER : gcc 4.3.3
   Address of local variables is not generated aptly .
   Lets take a sample code 
Example :
                int main ()
                {
                  int a , b, c;
                  a=10;
                  b=20;
                  c =a+b;
                  return 0;
               }

when I debug it with gdb  , address of variables a, b, c are not as 
intended .
All the local variables should be filled in between frame pointer and 
stack pointer ( stack is a top down stack).
Rather the local variables address are located 8 locations below stack 
pointer.

Can anyone point me to the apt solution for this problem. What macros 
should I  refer to for correct debugging information generated by compiler.
Thanks in advance
