>Description:
The following code is being rejected.
This is a regression wrt 3.0 and 3.1.
class A {
public:
A(){}
A( const A& a ){}
};
class B : public A
{
public:
B( int& s) : s_(s){}
int& s_;
};
int main()
{
int i;
B x1( i );
B x2( x1 );
}
$ /opt/bin/g++-32 x4.cc
x4.cc: In copy constructor `B::B(const B&)':
x4.cc:18: `const' qualifiers cannot be applied to `int&'
