Reproduction steps:
1. Open the attached “CrashRepro” project
2. Open the Unity Version Control window (Window > Unity Version Control)
3. Check one of the files under Assets/Free/Wooden Floor Pack
4. Click "CheckinChanges" button. You may need to dismiss a popup. Confirm it if so.
5. No crash? Go back to step 3. I can repro consistently when I do this about 5-7 times.
Expected result: The changes are checked in
Actual result: Unity Editor crashes. Editor.log states near the end that it ran out of memory.
