Yes, I do. This one is on top of it. The crash happens with
`05b36b04d74a` applied. All the crashes were reproduced with
build of `feffde684ac2`.
Honestly, `05b36b04d74a` looks a bit suspicious to me as it really
does not look to deal correctly with the issue to me. I was a bit
surprised/puzzled.
Anyways, I could reproduce the crash in a matter of half an hour. With
this fix the torture is surviving for 22 hours atm.
