* We got a break on an EnterMethodJIT crash!
** Users had been reporting crashes on Yahoo Mail Beta ({{bug|655660}}) and others.
** David Anderson was able to reproduce the crash and fix it.
** The bug was a too-small bitfield holding patch locations for ICs that could grow very large.
** This bug might be a good fraction of the EnterMethodJIT crashes we get.
* We're starting work on GC topcrashes
** Bill McCloskey is finishing a new Breakpad feature to snapshot stack traces at desired points (e.g., when GC runs) and put them in minidumps: {{bug|662646}}.
** Figuring out these crashes will take a while--we'll need to experiment with different measurements and analyze data over time.
