The problem is that the .bc file is correct, so it wouldn't do any good. 
It's only when I don't create the files that I have the problem (all in 
memory). The optimizer shouldn't happily eliminate variables that are 
accessed, though.

Anton gave me a hint, though, that solved my (stupid) mystery: I had 
switched to formatted_raw_output for my assembly file writing and didn't 
notice that I needed a flush(). The declarations at the end of the file 
were left off.
