Short description of error
Hello there, wonderful people of Blender development community!

I think the ability to edit multiple objects in the edit mode presented a set of new bugs. For example, all the time I create two separate Armatures with bones in them I can select them in edit mode and try parenting them. Which will cause an instant crash with no notification or errors. Here's the video of the bug:

I guess if I'm not allowed to do that I must get the error message and not crash instantly.

Exact steps for others to reproduce the error

- Create a scene
- Create two separate Armatures sets with one bone in each
- Select both Armatures
- Go to edit mode with both Armatures selected
- Select both bones from separate Armatures
- Press Ctrl P and parent them
- Crash with no error or notification

Thank you for your hard work!

I should note that the parent order seems to matter. I can only get it to crash when parenting bone A to bone B, but not bone B to bone A. However, even if it doesn't crash, the parenting doesn't work.
