Unity crashes when saving something while being out of space

Scene Management



Priority: 4Not yet prioritized for a release


Severity: 1Crash, freeze, data loss, work stops

To reproduce:
1) Have an almost full partition (I used a USB Drive for testing)
2) Create a project there
3) Finish filling up the partition so that it would be completely full (<2-4 mb of free space)
4) Try saving a scene so that you would go over the limit

Expected: Either Unity stops you from saving (like Build Process is stopped in the same circumstances) or informatively tells the problem while crashing
Actual: It just crashes with "data offset != file.GetPosition()", which doesn't make the problem clear

Reproduced in 5.4.0f3, 5.5.0p4, 5.6.0b4, 2017.1.0f3, 2017.2.0f3, 2017.3.0b9
