A recent Swift snapshot of Clang crashes when building CMark; repro script and preprocessed files attached to https://bugs.swift.org/browse/SR-10090.

(Admittedly Swift's copy of Clang is going to have branched a while ago, but it's still possible this hasn't been fixed. If it has, we'll track down the fix and cherry-pick it.)
