Hi Himani Ramesh,

Thanks for the new version. It looks like the embedded patch fails to
apply here:

ERROR: tiff-4.7.2-r0 do_patch: QA Issue: Fuzz detected:

Applying patch test_ifd_loop_detection-relative-images.patch

Hunk #1 succeeded at 45 with fuzz 2 (offset 11 lines).

Can you have a look at the issue?

Thanks,
Mathieu
