Seems [cos~] only gives expected results between -1024 and 1024. Above 1024 the frequency halves, halving again at 5120, etc. Below -1024 the frequency doubles, until chaos at -3072.
You didn't give as much info as you did on IRC. We found it to happen at 1*1024, 5*1024, 13*1024, 29*1024, 61*1024.that's (pow(2,n)-3)*1024 (starts at n=2 and doesn not include the negative point(s)).
