#9572 Leaking memory over time?

I worked with #9572 for several hours yesterday with no problems, and left it open overnight. This morning I started typing into the editor and before I had time to finish the first word, IDEA just disappeared. When I restarted it, it loaded and rescanned the whole project.

I started using it at about 09:45 this morning - here is the relevant part of the log covering the time it died and was restarted - no errors reported:
