Your question doesn't make sense because there's no such term
as active object in C++. As to whether destructors of auto
objects are called during stack unwinding (regardless of whether
a C++ exception is caught or not), the answer is - yes, unless
you've intentionally screwed it up yourself (like disabling C++
exception handling in the compiler options for example).

Hi Alexander,

Question 1 makes no sense.

Why question is not making senses? My question is whether destructor is
ensured to be called when there is uncaught exception during stack
unwinding.

(I think the answer is not ensure to be called.)

George

Question 1 makes no sense.

For question 2 - you are basically right, though it makes no difference
what caused the process to exit - exception or not. It's mostly academic
by now, but kernel handles were not released in Win 9x.

And a comment on my own. I hope you finish your C++ education
soon, because you are singlehandedly responsible for at least 50% of
the traffic in this group...

Hello everyone,

Just want to check whether my understanding is correct,

Both (1) and (2) only covers Windows C++ platform.

1. If there is uncaught exception, destructor is not ensured to be
called
for active object;

2. All the resources (handles, memory, etc.) for current process will
be
released when uncaught exception causing process to terminate.

thanks in advance,
George
