Yeah, I am not sure, your patch just reminded me of this. Maybe if the DWARF patch goes in, the bug could be closed. Given its age I would suppose this hasn't been needed very often. Relatedly, somewhere I have a patch that adds a name to every unwinder, so that you can tell what made the frame you're looking at. This can be handy when debugging unwinders. Tom
