My understanding is the same.  But we should not allow redisplay to kick
in before selected_frame is updated.

I don't oppose your patch and that's why I didn't comment it initially.
If you think it's urgent to fix this specific crash, push it.  But we
obviously might also let more serious bugs pass through that mechanism
then.  If Madhu has a simple recipe to reproduce the crash, we should
IMHO try to profit from it.  If he responds at all.
