I've tried your file 2.16.3 in a Win7 VM with 4GB and trying to reproduce your actions but didn't get a crash. I managed painfully to move a node of the coastline of western part of France. Note that I used a 64 bit build, and I noticed that the memory consumption goes up to 3 GB when you enable the Node tool (goes down to 300 MB once you finish all editing actions), so if you use a 32 bit build, a crash is not surprising. All the actions are super slow, particularly making a node active and moving it. There are clearly issues, with algorithms, data structures and memory use, when dealing with huge polygons. I also noticed that there's apparently always a core busy until you finish editing.
