Could you post a code snippet showing the API you are using that *does*
work to find a member function's definition from the call site when that
call site *isn't* in a subclass, or when the superclass isn't templated?
And then a code snippet showing the (hypothetical) API you would
*expect* to be able to use for your test case.

FYI for exploring the libclang API I found the python bindings, plus
ipython (an interactive python interpreter with tab-completion)
extremely helpful. See for example
http://lists.cs.uiuc.edu/pipermail/cfe-dev/2012-August/023449.html
-- judging from your rtags tool you either know this already, or don't
need it, but I thought I'd mention it just in case. :-)

Thanks,
Dave.
