I've tested your patch and it causes a qt-5.4 build failure
(also happens on trunk):
markus@x4 WebCore % cat Font.ii
namespace WTF
{
template <typename T> inline void deleteOwnedPtr (T *);
}
namespace WebCore
{
class TextLayout;
}
namespace WTF
{
template <>
void
deleteOwnedPtr (WebCore::TextLayout *)
{
}
}
(Without your patch:)
markus@x4 WebCore % g++ -c -O2 Font.ii
markus@x4 WebCore % nm Font.o
0000000000000000 T _ZN3WTF14deleteOwnedPtrIN7WebCore10TextLayoutEEEvPT_
(with patch applied)
markus@x4 WebCore % g++ -c -O2 Font.ii
markus@x4 WebCore % nm Font.o
markus@x4 WebCore %
