As long as you are prepared to deal with any fallout, go ahead. In any
case I doubt there are very many darktable users on arm64.

Well, take that up with the gcc maintainer, since that is where the
(fixed upstream) bug is.

Bug#1057472: darktable: diff for NMU version 4.4.2-1.1

[Boyuan Yang]

Package: darktable
Version: 4.4.2-1
Severity: normal
Tags: patch  pending
X-Debbugs-CC: brem...@debian.org by...@debian.org

Dear Debian darktable package maintainer,

I've prepared an NMU for darktable (versioned as 4.4.2-1.1) and
uploaded it to DELAYED/5. Please feel free to tell me if I
should delay it longer.

I am disabling the OpenMP support for now on arm64 so that it does not
block library transitions indefinitely. Currently it blocks the completion
of libavif transition, and transitively blocks jpeg-xl transition from
starting, etc. For a full list of blocked transition, check information on
https://tracker.debian.org/pkg/darktable . I don't think we should delay it
any longer given that no signs of bug solving is currently visible.

If you have any other idea, please let me know immediately and feel free
to stop my delayed upload using dcut. I would be more than welcome to have
some discussion so that we can get a proper solution.

Regards.
