Hi Richard,

Nobody replied because your question lacks immediate relevance to this 
mailing list.

You may have more luck if you pose your question in a way that relates 
to, and can be tried using stock LLVM/clang.

If you think there's a bug, you can also file a bug report at 
http://llvm.org/bugs/ including the steps needed to reproduce the issue.

Feel free to CC me in, hope we can set you in the right direction.

Alp.
