[Bug c/26118] New: avr-gcc (GCC) 3.4.5 Bug: copying structure through pointer will destroy the pointer

[cajus dot hahn at de dot abb dot com]

there is a bug in avr-gcc (GCC) 3.4.5, that comes with the latest WinAVR
distribution (20060125).
The  avr-gcc (GCC) 3.4.3, that comes with WinAVR 20050214 does NOT contain this
bug. 
The bug exists with and without optimization (I tried -O0 and -Os)
If you try to copy a structure with
 *struct_pointer = struct; 
the struct_pointer gets destroyed.
The assembler code generated seems to add one structure length foreach copied
byte to the pointer.
The complete code is attached. (there I use  *struct_pointer++, but it is the
same problem there).
