Ah, that's right. I went back and read the discussion from
January, and Florian Brandner explains there that the real
culprit is the lowering of GEP in the codegen prepare pass.
Florian, if you have worked more on this, we would be very interested
in your work. Serialization caused by memory references is a big
obstacle for us at the moment.
