Your back trace looks exactly like what I posted in
http://lists.nongnu.org/archive/html/qemu-devel/2018-12/msg05579.html .
No, I don’t think anybody has posted a fix for this so far. I know
other people saw similar issues.
I know what I have on my test branch (which contains various fixes to
make all iotests run or at least pass those which are terminally broken):
https://git.xanclic.moe/XanClic/qemu/commit/c52433f218c61ef608ab4d9abb56e1f705a3ae22
I have a lot of patches on my test branch. (15, to be exact.)
