I also tried messing around with the following:

int Func(void)
{
    std::jmp_buf jb;

    if ( 0 != setjmp(jb) )
    {
        // also do other stuff in here
        return 42;
    }

    auto monkey = [&jb](void)->void { std::longjmp(jb,1); };

    monkey();
}

but I think the other solutions make more sense. Or just throw and
catch an exception.
