System to evaluate and update objects for editing and animation.

Fun bug. But yes copy on write is heavily under development by @Sergey Sharybin (sergey) and nowhere ready for public consumption. Thus not open for bug reports.

Thank you for the report. Currently we are aware of many issues in 2.8 and actively working to fix them.
But since replying to reports takes time, we have decided to limit bug reports to module team members.
This is a limitation of the old depsgraph. It only supports links between objects and object data. Materials and textures however aren't included in that.

Whew... I was finally able to wake it up in the most bizarre way! If the driver is in this frozen state, you MUST add a variable that references an OBJECT ID Block and add some animation to object, then set the driver variable type to "Transform Channel". Trying to use an animated single property (such as evaluation time on a Path) will NOT work. Of course, this placeholder variable does not need to be used in your scripted expression, it simply sits there to prevent the driver's door from locking! :-)
Wow... this is insane. Even though I was able to successfully wake up the driver by adding a variable in a new project, in the original project that glitched, it has remained frozen. Still investigating why this bug is occurring. I tried the f76d49e latest build along with the 8928d9270f official 2.79a build and neither can wake up the drivers! The glitch had occurred in the earlier d640ce4 build.
I couldn't figure out why Blender drivers suddenly stopped working without explanation even with Auto Run Python Scripts checked. But I thank God for showing me it was because a no-longer-needed variable had been deleted. Well, now I know that Blender requires at least one variable to be present even if not been referenced for drivers to execute. :-) There definitely should be a default warning of "Must set at least 1 variable for driver to execute" when adding a scripted expression and no variable has been set.

Dependency cycles are resolved now.

Old dependency graph does not report dependency cycles happening inside of the rig. The fact that rig works in old depsgraph might be co-incident.

DepsgraphRelationBuilder::build_animdata_curves_targets() is incorrect.

I tested with blender-2.79-1d33843ea6b-linux-glibc219-x86_64 and there was no crash.
No, we'd have no time to check on such reports when making next release… If fixed in current master, we just close as fixed!

Same here, I don't remember however if we simply close theses bugs, or keep them marked as to be re-checked before 2.79a final release. @Bastien Montagne (mont29) ?
I have a crash with official 2.79 but no crash with master 1d33843

@Campbell Barton (campbellbarton), patch seems fine to me. Dont' see anything wrong with the resulting relations either.

@¿? (edtion) please be more specific in your bug reports, tags like Dependency Graph only mean issue is with a depsgraph, it does not imply at all that it is with the new one (or the old one). That’s why we ask our reporters that they follow our submission template and guidelines, read these tips about bug reports, and make a complete, valid bug report, with required info, precise description of the issue, precise steps to reproduce it, small and simple .blend and/or other files to do so if needed, etc.
We don't need a .blend file.
I am sorry for missing the tag and quickly triage the report as incomplete.
I assumed it was understood by the tags I used. I'm still assuming you knew that but since it's not happening, I believe I should stop assuming it:
Only managed to redo this in blender2.8, looks like pointer checks resolve, assigning to Sergey.
I did not manage to reproduce the crash on my machine with current master or 2.79.

@Joel Godin (FloridaJo) are you using the new depsgraph and a nightly build? it probably needs to be newer than the 14th of september.
Not seeing that here on OSX. Feather feathers, and V - A adds handles. Not sure if correctly but I see handles.
