Which audio device are you using? The HDMI port (imx-hdmi-soc-audio) or 
the analog port (sgtl5000) on the Wandboard? If you are indeed using the 
HDMI audio, could you try using the analog audio and see if the problem 
persists?

I reproduced the 'Illegal instruction' crashes you mention when using 
HDMI audio -- not only with `pulsesink' but also with `alsasink' 
depending on other unrelated particularities of the test-- but the 
problem disappeared as soon as I switched to the sgtl5000 audio.

Kind regards,
Marco.
