Follow-up Comment #1:

Problem is not reproducible. Tested with small c testcode as below with
following instruction:
simulavr -d atmega1284 -f master.o  --trace=/dev/stdout

results in:
master.o 0x0600: __do_copy_data                 LDI R17, 0x01

elpm is handled as expected.

If the problem is still present, feel free to reopen the entry again.
Please use the actual git master! Any older version is not maintained!
