Hopefully I'm not missing something┬╣, but the only "address" I can see
is the displacement of 0x32 (decimal 50). You'll have to place a
breakpoint, and read the register to see where the std would end up.
(Sorry, it's so long since I used simulavr, that I don't remember all
that it can do, but that much must be there.)

Have you been away from avr for a spell, Klaus? ;-)
