Figure out why the Xamarin garbage collector occasionally crashes #3
Description
Every once in a while, ActivityRecommender crashes for me. If I remember correctly, the error message is usually the same one from https://xamarin.github.io/bugzilla-archives/14/14339/bug.html : "SGEN: Assertion: should not be reached at sgen-scan-object.h:111"
It would be great if we could find a deterministic way to reproduce this issue so we could report it to Xamarin for them to fix.
Maybe we could find some way to run a deterministic stress test with a bunch of automatically generated data and see if that causes it to crash.
