In the example below, class definition B compiles when inheriting
"public A" but results in a compiler generated error when compiled
with "virtual public A", as shown below. Using g++ 1.36.0- release
of 10/2.
[2.51]lynx) cat test.cc
class A {
public:
int i;
int j;
A(int val1 = 100, int val2 = 200) : i(val1), j(val2) {}
};
class B : virtual public A {
public:
int k;
B(int val = 40) : A(42,43), k(val) {}
};
