I don't have it handy, sorry. This test seems to be failing in a lot of different places though. Can you try with a different compiler or arch and see if you can repro? If you look at the logs on the google buildbots, it looks like the instruction is coming up with a completely different immediate value.

I'm going to disable the test for now...
