I have a DNG file that causes a crash in LibRaw 0.19-Snapshot-20170812 (no problem with LibRaw 0.8.16). The crash happens in the "unpack" function.
I used the Visual Studio project provided in LibRaw 0.19-Snapshot-20170812 without changing any settings. I opened and compiled the project with Visual Studio 2010 Express in 32bit / release mode. I did the same with LibRaw 0.18.6 and got not problem.
I send you the file by WeTransfer right now. The owner of this image agrees that I send it to you this file for debug purpose but asked me to specify that it cannot be shared or published.
Thanks for your understanding and help.
