Hi all,
We just found a bug while compiling the following code. The derived template
class doens't know the pure virtual method from its parent class when this
template class has a method with the same name, but with different arguments:
class A {
public:
virtual void doit() = 0 ;
} ;
template <typename T>
class B: public A {
public:
virtual void doit(double) {}
} ;
class C: public B<double> {
public:
virtual void doit() {}
} ;
int main() {
A* a = new C ;
B<double>* b = new C ;
a->doit() ; // ok
// Compile error with gcc-3.4.3:
// error: no matching function for call to `B<double>::doit()'
// note: candidates are: void B<T>::doit(double) [with T = double]
b->doit() ;
}
