"Libraw is an external lib, actually the one that runs under dcraw. It is bundled in darktable to assure the version we are running. So, basically, this bug should be filled there so it us solved in the proper place. Also, we are using mostly rawspeed as the raw decoding library, and we are only using Libraw as a fallback. 

Anyway, thanks for the bug report."


So, I posted the warning to the LibRaw community and got this response

Hi,

thank you for report.

Darktable 1.1.3 uses (old) LibRaw 0.14.7. Consider switching to LibRaw 0.15 (currently in beta).

Hi,

LibRaw 0.15 is *very* stable. I use it in my RawDigger software (www.rawdigger.com) and in another program (currently in private testing, so no disclosure).
The only *unstable* thing is ABI and possible internals change. It may change in next several LibRaw 0.15 releases, so it is named 'beta'.
From darktable side this is not a problem, because darktable uses 'own' copy of LibRaw, so no binary compatibility with libraw.so is needed.

It would have been nice to note and follow the instructions of the next few lines seen below that are shown after that QA notice. Next time please open a bug upstream, thanks.

* Please do not file a Gentoo bug and instead report the above QA
* issues directly to the upstream developers of this software.
