<pre>The following code does not get a vtable emitted when compiling with clang
5.0.0 (release_50@310398). Removing the 'using mozilla::B' line causes it to be
emitted. The vtable is also emitted when not using '-g'
class FontInfoData;
class A {
void F(FontInfoData *aFontInfoData);
};
namespace mozilla {
struct B
{
A* mAttrs;
};
}
using mozilla::B;
using namespace mozilla;
class FontInfoData {
void Release() {
delete this;
}
virtual ~FontInfoData() {}
virtual void R();
};
void FontInfoData::R() {
}</pre>
