I never thought it was a bug in the library :)
I however throught (incorrectly) that copying an unassigned pointer was valid,
mainly as some other test case was considering constructing
std::vector<std::list<int>::iterator> v(1). Now I realise that in fact copying
an unassigned pointer is undefined behaviour, so of course the error is fine :)
Sorry
I'm still curious as to why the error doesn't appear if let g++ generate a
default constructor, as from my reading of 12.1/7, the default generated
constructor should be "ptr() {}", so the error should still appear. Am I reading
it wrong?
