Browsed the log and I’ve seem to have had a similar crash earlier in another song using my emu’s asio drivers:

My system has been unstable for a while now (see crash log from this thread: Experiencing Slowdown In Renoise ) and I’ve been pushing my tracking sometimes beyond being able to playback the song realtime, kind of like blind tracking 
, automating vst’s and hitting the 99% cpu. Because of the crashes I’m freezing tracks and that helps!
