Ok, now I launched avarice as follows:

avarice --debug --jtag3 --debugwire :4242 1> debug.log 2> debug.err

The two files created by this command are attached. avr-gdb is version 7.5.1 
according to "avr-gdb --version".

This is the debugging session with avr-gdb which generated the above log 
files:

This raises a few more questions:

*) What about this XML memory map? Could this be related to the problem?

*) It's interesting that the breakpoint gets two different addresses, is this 
normal behaviour?

*) Is there a list of controllers known to work with 
avarice+JTAGICE3+debugWIRE? I also have some other parts here for testing.
