There are a variety of Android opt R16 crashes on trunk currently. I think this is just one variety.

The trouble with Android R16 started with the bug 1228680 check-ins:

:sebastian -- can you have a look?

Okay, I'll have a look. Right now I can't imagine why the code from bug 1228680 might trigger this but I'll investigate.

I can't reproduce this issue on try anymore. I couldn't find any reason for this happening from the code so I just tried various partial reverting patches on try but recently they are all green, even with no changes.
