results in this error when i want to start bro:

Please send the full script exhibiting this problem. I actually *did*
test my suggestion and it works for me, and I just fed the above into Bro
and it didn't generate any error message.

here:

######### test.bro

global myfunc: function(t: table[addr] of count, idx: any): interval;

global tcp_host_state: table[addr] of count &default=0 &write_expire=1day
&expire_func=myfunc;

function myfunc(t: table[addr] of count, idx: any): interval {
        local srcIP: addr;
        srcIP = idx;
        print t[srcIP];
        return 0secs;
}

result:

christoph:/usr/local/bro # ./bin/bro -i eth0 test
policy/test.bro, line 7 (srcIP = idx): error, type clash in assignment

thanx
