Upstream bug report with Apple: https://openradar.appspot.com/FB9733712

The OSS folks I spoke to seemed to think it was a bug, and so far the radar has
not been closed as invalid yet.

However, this change in clang seems to suggest it might be deprecated to use
mod_term_funcs anyway: https://reviews.llvm.org/D45578
