Is clear that you don't understand the issue here. It's *IMPOSSIBLE* to get a stack trace in a debugger (i.e., a live stack trace) or a core dump that way. So, yes, it way too much to ask :) > It comes back to doing a sensible thing by default. main() without a > try/catch is common in short scripts.
