reduced:
#pragma GCC diagnostic ignored "-Wunused-parameter"
template <class>
struct KeyValue
{
virtual void serialize(int a) const
{
}
};
void f()
{
KeyValue<int> values;
}
#pragma GCC diagnostic warning "-Wunused-parameter"
The template instantiation is at the end of the file, after the warning has
been re-enabled.
There's no warning with 4.6.0
