Hi Dan,

Can you narrow down the problem a bit more?

Is this only with the RC2? Or also with RC1? Does it work with 3.8.0
or 3.8.1? Some version of trunk?

Also, that is a *very* high level description of the problem and it's
really hard to reproduce it. This may be a problem in backwards
compatibility of libclang (which shouldn't happen), or it could be
that the completeAt usage was assuming something that wasn't true.

If you could create a bug explaining the process, stating the most
recent version that you can see it working, and how to reproduce
without any additional tools (ie. by using libclang directly,
preferably with a piece of code that does it), then Clang folks could
have a better look at that.

cheers,
--renato
