<pre>The declaration of A::f has a const. The definition doesn't.
template <typename T>
struct A
{
void f(const int);
};
template <typename T>
void A<T>::f(int x)
{
x = 0;
}
void f()
{
A<float> a;
a.f(0);
}
Clang produces an error:
test.cpp:10:7: error: read-only variable is not assignable
x = 0;
~ ^
test.cpp:26:7: note: in instantiation of member function 'A<float>::f'
requested here
a.f(0);
^
This doesn't seem to be a correct behavior. It only happens for template
classes. In exact the same situation with a regular class everything compiles
well.
struct B
{
void f(const int);
};
void B::f(int x)
{
x = 0;
}
void f()
{
B b;
b.f(0);
}
GCC compiles both examples without an error.</pre>
