Hi Greg .. Does it go for the tools built on top of LLDB (e.g. in my case where feature library is not a part of liblldb shared lib but built on top of it)? If yes, then I will proceed to remove std::vector from C++ public API of the tool and create a new class for it.

I want to provide a python interface for the tool's C++ public API as well so that the API can be used in python modules as well. Therefore, I think typemapping to list() will not solve the problem. Am I right?

Probably, I didn't understand this comment of yours. We are not exporting python binding for Intel PT data. It is a python binding for Tool's C++ API and this Tool is built on top of LLDB. Did I answer your question? Please let me know if I misunderstood your comment.
