Can you please provide a backtrace? I couldn't reproduce this in a quick
attempt, so I can't get it myself.

The commit dafac85ed4f43d694c1b438ec6d14e18d225e600 works fine, I git diff the two dafac85ed4f43d694c1b438ec6d14e18d225e600 and ea25559830a1a025e534dea634158c0141c71894, and revert qemu-img.c to dafac85ed4f43d694c1b438ec6d14e18d225e600 , then everything is OK.

Thanks,
Xudong
