I've got the latest master as of 2 days ago building and running on a pandaboard. I've noticed that I've been seeing a *LOT* of cases where apps will just close on start a few times, and finally open. Also navigating around in the settings application will cause a crash.
Most of the time it appears to be a crash in libhwui, which romain claims are bugs that have very likely been fixed, but not included in master branch (yet). I've captured another opening an activity in our application... it failed to open 3 times (with the following errror), and succeeded on the 4th.
