No, that would be an obviously stupid position to take. I don't understand why you even say such a thing. > Why would code, essential for debug information consumers that are > part of larger systems to work correctly, deserve any less attention > to correctness? Because for most people the use of debug information is to use it in a debugger. And for those people, correct information at line positions suffices. Even the use you mentioned of doing backtraces only requires adding the notes around function calls, not around every line, unless you enable -fnon-call-exceptions. If you want to work on supporting this controlled by an option (-g4?), that is fine with me. Ian
