System Information
Operating system: Linux-5.4.44-1-MANJARO-x86_64-with-glibc2.29 64 Bits
Graphics card: AMD VERDE (DRM 2.50.0, 5.4.44-1-MANJARO, LLVM 10.0.0) X.Org 4.5 (Core Profile) Mesa 20.0.7

Blender Version
Broken: version: 2.90.0 Alpha, branch: master, commit date: 2020-07-03 17:12, hash: 185fe9cd8b
Worked: 2.83

Short description of error
Blender 2.90 crashes on save if there is a library override and it crashes if the parameters of the library override are edited.
There is also another crash triggered by switching to a different scene

Exact steps for others to reproduce the error
Crash #1/#2 (save/edit)

link the material from the source file {F8662182}(File - Link - MAT_Source.blend - Materials - MAT_from2.90)
assign the linked material to the default cube
add a library override to the linked material (Outliner - Blender File mode - select linked material - Add Library Override via right-click menu)
try saving the project OR try changing a parameter like the color
crash

Crash #3 (scene switch)

steps 1-3 from above
create new scene (or switch to a different existing scene)
undo (so you are back in the original scene)
switch to a different scene
crash

I confirm the crash when trying to save the file.

Overriding materials are not fully supported currently, nodes are as usual an issue... Will have a look though, should at least not crash

Thanks! So basically you blocked using the override but not it's creation? Because while the testscenes do no longer cash, I still can't save my main project that already includes an overridden linked material (luckily, autosave does work).
Also

shift-clicking the material override icon of a linked material in the material properties editor
undo
shift-clicking the material override icon again
crashes blender (sometimes requires going back and forth multiple times).

Just found another crash:
In the outliner, in Blender File mode, select Copy in the right-click menu of an overridden data-block.

Please consider hiding library overrides under experimental features until it is more complete.

The copying crash is solved (version: 2.90.0 Alpha, branch: master, commit date: 2020-07-15 09:06, hash: e8b26a0501), but the other isn't. It seems to crash more reliably with:

shift-clicking the material override icon of a linked material in the material properties editor
click the icon again (to make fully local)
undo
click the icon again (to make fully local)
crash
Should I file a separate report or does this belong to "known issue"?

Please create a new report yes, one issue per report. ;)
