Various GCDM unit tests fail under UBSan. I tried to debug a few, and for several of the issues the issue is in libjpeg code.

What upstream libjpeg does GDCM use currently? It's possible these issues are already fixed upstream.

It looks like GDCM is using the old libjpeg 6b? If so, maybe it should switch to https://github.com/libjpeg-turbo/libjpeg-turbo ?

Mathieu, any thoughts on this? The old libjpeg is one of the last sources of UBSan errors for me...
