pre-processed source that generates error

I am not sure what the root cause that triggered this error was, but the
pre-processed code is less than 8000 lines and I shouldn't be seeing an
internal compiler error.

Mainline simply rejects the code with no ICE. If you have reasons to believe
the code is valid, please file a separate PR with a small reproducer, thanks.
