Hi, I noticed that although 'make check-block' was passing happily I was seeing a kernel log showing a qemu-img seg:
[Fri Aug 14 12:26:07 2015] qemu-img[7725]: segfault at 0 ip (null) sp 00007ffff73e9a98 error 14 in qemu-img[55f707577000+f8000] The case that fails is: run_qemu_img amend -f qcow2 -o backing_file=/home/dgilbert/try-world3/tests/qemu-iotests/scratch/t.qcow2, -o help /home/dgilbert/try-world3/tests/qemu-iotests/scratch/t.qcow2 and I think the problem is due to a disagreement between 626f84f3 - qemu-img amend: Support multiple -o options and 76a3a34d - qemu-img: Add progress output for amend In the 'Invalid option list' case it goto's out skipping the qemu_progress_init, but the out: clause does a qemu_progress_end that then segs. However, I've not dug into why the testcase code didn't spot it, which seems a more important problem. Dave -- Dr. David Alan Gilbert / dgilb...@redhat.com / Manchester, UK
