Ok, this cast should be a no-op, stricly speaking. Here is some test
code:
#include <iostream.h>
class foo {
public:
foo() { cerr << "here\n"; }
void f1();
};
void foo::f1() {
}
void bar(const foo& a)
{
}
int main()
{
foo a;
cerr << "1\n";
bar(a);
cerr << "2\n";
bar((foo)a);
cerr << "3\n";
bar(foo(a));
cerr << "4\n";
a.f1();
cerr << "5\n";
((foo)a).f1();
cerr << "6\n";
}
Here is the result for me:
here
1
2
3
4
5
6
I'd say that the problem is elsewhere or that another subtelty is
involved and beyond my understanding.
Cheers
