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.
