The patch 23bdb6f7ce73c33f96449e43b4cae01e55f79ae1 appears to be
segfaulting `qemu-img` at `replay_mutex_lock`.
The problem does not happen on the patch base
bc2943d6caf787e1c9a5f3109cdb98f37630b89e
The command is:
buildroot/output.x86_64~/images
../host/bin/qemu-img convert -f raw -O qcow2 rootfs.ext2 rootfs.ext2.qcow2
Aborted (core dumped)
and the backtrace:
