I checked again, and the obj file seems to be OK. So I'm wrong about 
that -- it's just an OPTLINK problem.

Yeah. But it probably won't get fixed unless you can simplify it.
Mind you, OPTLINK is unlikely to get fixed, anyway. But maybe Walter can 
change DMD slightly to work around the optlink bug.

#1439 shows that something bad happens when the symbol length is a 
particular length (out-by-1 error?). I think this is quite likely to be 
the same issue, since you have so many templates in there.
