There are valid situations where the most recent stack frame is unknown (for example, incorrectly attempting to execute stack or heap). Also there are times when the crash happens earlier, and various handlers are involved. Perhaps change it to 8 layers of "stacktop", and allow for it to be "valid" if at least 4 aren't "??"?
