Hi,

It's great to finally see more interest for getting Clang on Windows
working with Boost.

As for your specific issues, I'm not quite sure what could be causing
that... I have been successfully compiling and using Boost.Test for my
project's testing.

I know that recently there have been some big changes on trunk to
Boost.Test which have caused crashes under Clang on some platforms (which
included Windows when I tested it), so yesterday (or the day before, I
forget) I switched to the release branch temporarily (I couldn't be
bothered finding the offending commit at the time as I was busy fixing
something else) and had no issues compiling there... Perhaps you could try
the release branch and see if you're having the same issues? If so, your
issues may be caused by the recent unstable Boost.Test change(s)...

If that's not it though, please let me know and I'll set up a VM with a
clean environment and try compiling under that to make sure there's nothing
I've forgotten about (as I probably have!), then I'll post a full list of
steps and scripts I used so others can reproduce my results. It will take
me a few days to do this though as I am going away today and won't have
access to my machine for 2 days.

Thanks, and good luck!
