Replying to [comment:5 Elon Musk]:

In fact this happens on linux too and in fact the tiff file is bitperfect
with windows :) sha256sum of the file itself is
D0755FDC28347A1BF7354CFF1276227B82458F5D0B319A1E92784B9331D4D578
and md5 of decoding raw rgb48le is b97e3124afd8ee85202af35833289d63.
Same happens with debian default veiwer.
May be a bug in gcc 11.2.0 and 11.3, that is a buggy piece of 💩💩:

Try 12.1 gcc and -fno-tree-loop-vectorize.
All tested on https://github.com/BtbN/FFmpeg-Builds
