I'll make sure you get one.

Aditya finally has something reproducible on trunk that's huge (~25MB
bitcode).  He's just running bugpoint now.  Let's hope it shrinks a bit?

Our lab.llvm.org LTO builder [1] would reproduce it, but the config
change I made yesterday in our ailing public lab didn't seem to take
effect -- I must have restarted the wrong buildmaster or something.
I'll look into it.
