I don't have an answer for that. But although it would help in this
particular problem, it would just make the other problem that I'm
trying to fix latent until we run into an even more convoluted
testcase.

The testcase attached to the bugzilla that I mentioned does #include
some headers, but it compiled just fine with -isystem /usr/include on
my GNU/Linux/x86_64 system. If you'd like more than that, I'd be
happy to send you a preprocessed testcase.
