jasonmolenda added a comment. I guess the other comment I would make is whether we should have a new ivar, instead of using the unused 0th bit of search_offset.
fwiw I wasn't real clear in my previous comment. As you say in the title of this, you're trying to backtrace through a case where you have no symbol file, and I'm guessing the Windows ABI doesn't use a frame pointer register (rbp) that is is spilled to stack at the start of a stack frame by convention. The ArchitecturalDefaultUnwindPlan's that we use on ABIs where you see saved-pc followed by saved-fp can do a stack walk following the chain of those two spilled registers pretty reliably, once they're off of the leaf frame. This isn't the case on Windows right. You have nothing but a saved return address, and the stack pointer is not spilled unless there's some kind of variable length stack frame I'm guessing.
