can someone confirm internal compiler error in a following code (both VS2005
and VS2003):
#include <iostream
class worker_base
{
public:
virtual int execute() const = 0;
};
class worker_impl: public worker_base
{
private:
int value;
public:
worker_impl(const worker_impl &other): value(other.value)
{
std::cout << "copy constructor, value = " << value << std::endl;
}
worker_impl(int value): value(value)
{
std::cout << "constructor, value = " << value << std::endl;
}
// If in VC 2003 to omit destructor, compilation succeeds, always.
~worker_impl()
{
std::cout << "destructor, value = " << value << std::endl;
}
virtual int execute() const { return value; }
};
struct worker_ref
{
const worker_base &worker;
operator const worker_base & () const { return worker; }
};
int func(const worker_ref args[], int size)
{
int result = 0;
for(int i = 0; i < size; i++)
{
const worker_base &worker = args[i];
result += worker.execute();
}
return result;
}
template<int size>
inline int func(const worker_ref (&args)[size])
{
return func(args, size);
}
int main(int argc, char* argv[])
{
#if 1 // ICE
const worker_ref args[] =
{
worker_impl(1), worker_impl(2), worker_impl(3)
};
#else // ICE
const worker_base &w1 = worker_impl(1);
const worker_base &w2 = worker_impl(2);
const worker_ref args[] =
{
w1, w2, worker_impl(3)
};
#endif // ICE
int result = func(args);
std::cout << result << std::endl;
return 0;
}
Thanks in advance.
