The following code results in an error:
namespace Foo { template <typename T> void foo();}
struct Bar
{
friend void Foo::foo<int>();
};
The error is:
/home/stefan/friend.cc:4: error: Âvoid Foo::foo()Â should have been declared
inside ÂFooÂ
I've briefly attempted to debug this. Here are my findings:
At some point set_decl_namespace() is called for the friend
declaration, which itself then checks the function against
existing declarations in an iteration over the overload set.
In case of a non-templated function, decls_match() would return
true, but for the above function template it doesn't match,
and so we enter the 'complain' label.
Sorry I wasn't able to decipher the actual tree comparisons.
HTH...
