[Cin] Simplest demo of BT 638 crash

[Andrew Randrianasulu]

Phyllis, can you check HV's version of delayaudio plugin functions?

https://github.com/heroineworshiper/hvirtual/blob/457c27f1786a83d43ad205478e4389f760c4fdf9/plugins/delayaudio/delayaudio.C

they slightly different, esp. in memcpy parts.
I'll try to test this idea myself, sometime this day.
