[1.1.72] Segmentation fault when exiting while non-blocking save

[thibf]

While saving the game with SE with the non-blocking save enabled, I pressed exit before the end of the save which triggered a segmentation fault.
This happened on my save but also I reproduced it just using a "labo" save, so this is not specific to my save.

Non blocking saving is not supported, see 3636.
