I did not include a preprocessed file, as the problem goes away if you
preprocess it and run on the preprocessed file.

Instead, I have built a tarfile of all the include files touched in the build, 
and a script that uses -nostdinc -Ifoo -Ibar ... which reproduces the problem 
on other platforms.

As I mentioned this is a very hard to reproduce bug.

Hopefully the attached tarfile makes it clear; unpack it in an empty 
directory, and run ./reproduce_it (a shell script).
