Can't speak for other people, but I remember experimenting with glibc's backtrace(3) and being so underwhelmed by the usefulness of the information presented that I thought incorporating it would be mostly a waste of effort. Maybe there's an argument that it's better than nothing at all; but I think we'd still be driven to asking people to get stack traces with better tools. regards, tom lane
