did you try git/unstable ppa with these images? the jpg are unfortunately not helping to reproduce the issue on dev side. there have been some changes to that code in the last couple of weeks.

Ok, I will try the git PPA and report back with uploaded .raw images :)

So I installed the git version from PPA and it's still the same. Should I upload the .raw images?

Hello,

I also got this issue when trying to profile my Nikon D5100 for the new denoise module...

The raw image is composed of a dark zone and a light bulb
When importing it into darktable :
- If no module is selected/enabled : the light bulb is pink
- If the module "base_curve" or "highlight reconstruction" is enabled, then the light bulb appears correctly...
(I tried enabling a few others, but light bulb was still more or less pink...)
It seems to appears on over-saturated parts of the photo.

If it can help, I uploaded the raw file + exports on this url : http://fabiphoto.free.fr/darktable/darktable_pink.tar.gz

Note : darktable was built from git repo (last commit : a113cdb)

Any news on this one? I think I can remember some issues with our HDR creation code. No idea what the current state is though.

There were some changes in the HDR merging code, so hopefully this is fixed.
Could you please test and report any (new?) issues if you could find them.
