Thanks :)

It should apply to any avr-gcc version (and even other compilers, for 
that matter)...

Thanks for reporting this. Using your simple test case I was able to 
find out the (brown paper) bug :P

Attached is a new version with the correction, that runs your test case 
just fine.

For extra debug information, you can uncomment the line (in 
"log_dump_line()"):
        //printf("%s\n", log_data[cur_log_pos]);

I'm starting to build a simple debug log, that can be used to track 
down why a test case ABORTED, by showing the last N instructions 
executed with the values moved from where to where.

The output is still very raw, but I intend to improve it at least by 
using symbolic constants (Rn, SREG, etc.).

Enjoy,
