That approach looks more aligned to V8's needs. I will see if I can cook up a patch based on Alexander's work that does the same thing in Guile and write an unwinder for V8. I will let you know when I have this done. Of course I do not intend to block Alexander's work in any way, but perhaps this could provide additional feedback about the use case. Alexander do you have your work in a git repository anywhere? It might be easier to coordinate, if that's a thing you are interested in, and to track changes in your work as you react to Doug et al's feedback. I sometimes sync up to this tree, FWIW: https://github.com/andywingo/binutils-gdb/commits/master Regards, Andy
