SYMPTOMS
At the point where a class template is expanded using the new operator to a nested class, the compiler reports the following errors:
STATUS
This bug was corrected in Microsoft Visual C++, version 6.0.
RESOLUTION
There are two possible workarounds to this problem. Each is stated in terms of the sample code below:
- Remove t(new T()) from the initializer list and add t = new T(); to the body of the constructor. This workaround assumes class T is not a reference or a constant pointer.
- Change the definitions of class A and class B so that B is no longer nested in the definition of A.
Sample Code
/* Compile options needed: None */
template <class T> class C
{
public:
C();
private:
T *t;
};
template <class T> C<T>::C() : t(new T()) // error
{
}
lass A
{
public:
class B
{
};
};
main()
{
C<A::B> c;
return 0;
}
