We touched a file on disk and deleted it on entering background. If it exists at startup, last run was a crash. Not a great solution, but gave us some idea of # of crashes not caught by our crash reporting.
We do this for various other reasons (clearing possibly corrupted state, etc), but we've never uploaded the statistics to the servers. We may begin doing this in the future.
