(Sorry for reusing the thread)
template<typename, unsigned = 0>
struct __attribute__((type_visibility("default"))) extent;

gets printed as:

template<typename, unsigned = 0>
struct __attribute__((type_visibility(0))) extent;

(and it doesn't compiler because a string is expected) Is that by design 
or a bug?
