this usage triggers multitrack recording mode in ecasound (ecasound will 
try to align recording of testin.wav to playout of testout.wav), and the 
symptoms sound like an issue with this mechanism.

I couldn't reproduce this with my setup (ice1712), so could you retry the 
test with "-z:notintbuf"? If the problem still persists, can you send me 
(may be large, so please send offline) logs when run with "-dd"?
