I've programmed some time in C and I'm trying to switch to
C++ and I'm having problems with using the exceptions.
DJGPP crashes when I try this:

/*************************/
class Obj
{
    Obj()
    {
        throw 0;
    }
};

int Test ()
{
    Obj *o;

    try {
        o = new Obj;
    }
    catch (...) {
        return -1;
    }

    delete o;
    return 0;
}

int main ()
{
    if ( Test() != 0 )
        printf ( "\nError!" );
    return 0;
}
/*************************/

I know this is poor use of exceptions anyway, but would need
this kind of system because when I create objects, I can't
otherwise know if there was a problem in constructor. Can
anybody give me a hint how this should be done in the right
way.

Please don't comment the use of printf() in a C++ program...

By the way I would also like to know are you guys always
freeing up all the allocated memory when your program gets
an error, or are you just quitting with exit() or some
similar way?


Thanks.
