OK. Not important.

Well, looking at the preprocessed sources, I don't see it there. So I
must've been wrong about that all along.

I gave you the exact command to launch that test. What more do you

W.R.T. the above paragraph, I'm sorry. I must've mis-analyzed the
situation. I don't think the crash is your problem exactly; it's
surely a codegen bug. However, I believe it's in your power to work
around the bug.

The only compile-time problem here is in the compiler. You can only
experience that problem at runtime :)
