Well, I've managed to do enough quirky things to kick the console into a usable
mode, but trying to do a 'trace' gives a SSC breakpoint. At this point I
checked the code to discover:
void
db_stack_trace_cmd(db_expr_t addr, boolean_t have_addr, db_expr_t count, char *m
odif)
{
}
Hmm, guess that still needs to be implemented. :-P
