I think here I am facing issue of something like thread context. I need to somehow get context of the 2nd thread / suspend 2nd thread, read callstack and resume again 2nd thread. I am not sure of these and even I am wondering how to do this from my 1st thread.
what I did once for a similar problem was have each thread generate it's own backtrace. I installed signal handlers for sigusr1 for each thread at startup and generate the backtrace from the signal handler. this wasn't using libunwind but perhaps the idea is useful?
