Unity throws out Fatal Error: Callback registration failed kMaxCallback
Unity throws out Fatal Error: "Callback registration failed kMaxCallback" after working with the project for 30 minutes or more. It appears randomly.
Steps:
1. Actively use Unity for more than 30 minutes
Actual: Unity continues to work
Result: Unity crashes with Fatal Error.
Reproducible with: 2017.1.4f1, 2017.2.3p1, 2017.4.4f1, 2018.1.3f1, 2018.2.0b6
Note:
Reproduced on macOS, Windows, Linux.
Bug Report window does not appear.
Scene files are not restored after reopening Unity so all not saved Scenes are lost.

Tried the latest 2018.2.5f1 which claims to fix the issue, however unity crashed and quietly closed with no error at all this time. It never did so like this in previous versions so it could be related or simply a bad fix.

This is not resolved. Please make a new listing. I'm having this issue in 2018.2.3f1.
The last time it happened I had just saved in the last 10 seconds. Is there a relationship to actually saving? -

Happens on latest Unity version (2018.2.3f1). Happens very often (once a day), and everything not saved is lost. Unity also doesn't prompt to send a report (might have been removed from current versions of Unity).
As an aside, it's really bad form to forbid users from voting on an issue that is "solved in a future version", when the issue has been happening since Unity 5 at least and still happens.

It happenes at least once a day, Unity 2018.2.2f1, Windows 10. Last line in callstack is `UnityEditor.Handles:DrawLine(Vector3, Vector3)`. This method was called by my code from OnGUI().

"Voting Disabled for Resolved Issues (Fixed)"
This, most certainly, is not resolved. Just like everyone else here, it keeps happening randomly after I save a script and come back into the Unity Editor. Fortunately I've gotten in the habit of saving my scene after every single change.
