source causing error
The following code (which is not legal anyway, I think):
struct A
{
void delete_foo();
};
struct B : public A
{
using A::delete_foo;
};
struct Foo { friend void B::delete_foo(); private: ~Foo() { } };
results in an llvm_unreachable being hit in clang trunk; similar results are
obtained when friending a namespace-scope using declaration.
I've debugged the error and made a small patch which seems to resolve the issue
(friendusing.patch); this makes the code trigger an error (</pre>
