Exception handling when using \SUBSYSTEM:WINDOWS

Question

It appears that exceptions aren't caught when running in release mode with \SUBSYSTEM:WINDOWS.  The application will quickly exit with no warnings at all.  If I switch to debug mode and run the app, the exception is caught.

    try
    {
        AfxThrowInvalidArgException();
    }
    catch(...)
    {
        printf("it worked");
        Sleep(5000);
    }

What's going on here?  How am I supposed to handle this?

Answer 1

You'll likely get more helpful replies if you let us know which compiler
and version you're using.

Have you tried it with a different throw? e.g. -

try {
    throw 1;
    }
   
If so, what happened?

You say you're using

\SUBSYSTEM:WINDOWS

but you are trying to use printf().
Have you attached a console to your program?

If not, where is stdout to go?

Try using a MessageBox() instead.

If using a recent version of VC++ such as 2008, check the settings under
Debug, Exceptions
and see if they are different for debug vs release builds.

Hello Poonaka,

I performed a test on my side, but I cannot reproduce this issue.

To narrow down the issue, please create a new project to see if the issue still happens. This can help us isolate if the issue is specific to the project. Please compare the project configuration for Debug and Release mode and see the difference. You can also paste the setting here.
