The respective code after preprocessing is:

  ; Correct EEPROM address to read from data space.
 subi r22, lo8(-(0x1000))
 sbci eepr_hi, hi8(-(0x1000))

So somehow, that "eepr_hi" should look different, I guess.

This is broken in both, HEAD as well as the 1.6 branch.

(I'm currently working on something different, so I cannot track

Never trust an operating system you don't have sources for. ;-)
