After getting Win7-cygwin build of gcc latest trunk built, I was able to do
some more testing. I could then reproduce another segfault. As Janne
suggested and I certainly agree, the following simple patch clears this second
segfault. It is interesting that the Windows/cygwin execution behaves
differently and the opp->file somewhere is getting touched or not initialized.

I will commit this sometime tomorrow.
