I assume that you are talking about the 'core_avr_dump.core' file and
not that simulavr is seg faulting. ;-)

I haven't looked at one of those files in a really long time. It's
just a dump of the state of the avr at the time of the dump.

About the only thing you can do with it is look at it with a text
editor. ;-)

Way back before I added the gdbserver mode, the dump file was the only
way to look at the state of the program being simulated. It's really
been obsoleted by the disp programs and gdb support.
