qemu-img: 'amend -o compat=0.10' command failed with segfault on the fuzzed image
qemu-img amend -o compat=0.10' failed with a segmentation fault on the fuzzed image.
Sequence:
1. Unpack the attached archive, make a copy of test.img
2. Put copy.img and backing_img.qed in the same directory
3. Execute
qemu-img amend -o compat=0.10 -f qcow2 copy.img
Result: qemu-img was killed by SIGSEGV.
Traces can be found in the attached archive.
qemu.git HEAD 2d591ce2aeebf
Hi,
being on 2d591ce2aeebf, I rather receive "qemu-img: Error while amending options: File too large". Judging from the traces, though, this issue (the segfault at least) should be fixed by my "[PATCH v3 0/7] block/qcow2: Improve zero cluster expansion" series anyway (when merged eventually).

Hi,
Well, I still (on 2.2.0-rc2) receive "File too large", so I guess that's the fix.
