Did you perhaps forget to extract both, text and data with objcopy?
Then you won't have initialized data...

address@hidden 1389% cat foo.s
        .section        .text
        rjmp    .
        .section        .data
        .byte   42
address@hidden 1390% avr-as -o foo.o foo.s
address@hidden 1391% avr-size foo.o
   text    data     bss     dec     hex filename
      2       1       0       3       3 foo.o
address@hidden 1392% avr-ld -o foo foo.o
address@hidden 1393% avr-size foo
   text    data     bss     dec     hex filename
      2       2       0       4       4 foo
address@hidden 1394% avr-objcopy -O binary foo foo.bin
address@hidden 1395% ls -l foo.bin
-rwxrwxr-x  1 j  wheel  4 Feb 10 15:30 foo.bin*
address@hidden 1396% hd foo.bin
