This test currently works fine for me. Do we know why this is failing for you and not for others?

It' has been failing on buildbot at least for a week -http://lab.llvm.org:8011/builders/lldb-x86_64-darwin-13.4/builds/3919
I suspect it has something to do with clang version because running "expr @import Darwin; 3" from lldb shell is failing for the same reason:

(lldb) expr @import Darwin; 3

error: import of C++ module 'Darwin.machine.types' appears within extern "C" language linkage specification

extern "C" language linkage specification begins here

import of C++ module 'Darwin.cdefs' appears within extern "C" language linkage specification

extern "C" language linkage specification begins here

I'm running on OSX 10.10 and clang version is:

Apple LLVM version 6.0 (clang-600.0.57) (based on LLVM 3.5svn)

Target: x86_64-apple-darwin14.4.0

Thread model: posix

Updated XCode to 3.6 - works as expected.
