Public bug reported:
The two attached files cause 'qemu-img info' to consume lots of time and
memory. Around 10-12 seconds of CPU time, and around 3-4 GB of heap.

Looking through old bug tickets... can you still reproduce this issue
with the latest version of QEMU? Or could we close this ticket nowadays?
