Oh you're right.  It works in C++ because C++ doesn't auto-report uncaught
exceptions, so when one passes out of main the process exits in some special
manner that preserves the call stack.  What I don't get is why this works with
object dtors that are run as the stack unwinds though.  In any case,  druntime
has an extern (C) bool called rt_trapExceptions that is used by debuggers to
enable some of this functionality, but it has to be set very early in the
startup process.  I guess I'll have to think about this one some more.
