Er, hang on, this is a crash in Clang. Did you mean to file it at https://bugs.llvm.org ?

@belkadan I really don't know what is the policy of the swift fork https://github.com/apple/swift-clang I really don't know.

Fair enough. The intent is that if the issue doesn't involve any Swift stuff, it's an llvm.org bug, but deciding whether something failing in Clang is or isn't Swift-related isn't something an average user should have to do. The Swift project is still responsible for the Clang we ship in Swift toolchains.

Do you want to file this over at bugs.llvm.org (so you can keep track of it) or should I?

@krzyzanowskim I haven't had any problems when building cmark with clang recently, can we consider this issue resolved?

yea, I don't know how to validate this today. Maybe It's not a problem anymore.
