Follow-up Comment #1, bug #55217 (project gnuastro):

Currently, this can be fixed by flipping the image along the problematic axis
('--flip=1,0' or '--flip=0,1'). In Commit 6dc1fd447fd
a warning has been added to explain the problem.

But unfortunately '--flip' has to be called in a separate/prior call to Warp,
it can't be in the same call, because we only implement the warping matrix in
the WCS at the end of all rotations. So one useful step in this bug may be to
apply the WCS correction after each separate warp.
