Sorry for no response, I am busy with no_hz_full. I did saw such crashes but addressed by my own in past. I thought I was related to my setup and pressing time line to demo work in past so ignored. Since you too able emulate it therefore file a bug per mike suggested link, assign to me and I'll respond per my bandwidth.
Thanks.
