I have had a quick look at the objectfile with
avr-readelf -w
and found that global and static variables are in locations that are way beyond
the atmega128's 4K of flash memory.
It seems that flash addresses in the debuginformation are no longer subtracted
by 0x800000. (The flash offset used by avr-gcc)
For example, the last_baud_rate variable quite early in the objectfile is stated
to be at address 0x80019c:
<2><851>: Abbrev Number: 21 (DW_TAG_variable)
DW_AT_name : (indirect string, offset: 0x188): last_baud_rate
DW_AT_decl_file : 22
DW_AT_decl_line : 710
DW_AT_type : <2c>
DW_AT_location : 5 byte block: 3 9c 1 80 0 (DW_OP_addr: 80019c)
Probably, 0x19c is the correct address.
If you can fix this, I think we are done. (except maybe for similar problems
with the eeprom segment)
