An unhandled exception indicates a bug, so it is useful to get a dump of the program state at the point at which the unhandled exception is thrown. So some implementations call terminate() immediately, which will typically generate such a dump. However, simple exception-handling implementations based on setjmp and longjmp cannot search for a matching handler without unwinding as they go, so by the time such an implementation determines that an exception will not be handled it has already unwound the stack. The standard committee chose not to disallow either of these implementation techniques. --- [ comp.std.c++ is moderated. To submit articles, try just posting with ] [ your news-reader.
