Re: [patch] Fix libstdc++/36962
Paolo Carlini:
I think that the difference is detectable with get_deleter though.
If you can figure out a possible testcase, I would appreciate that.
Something like (untested, sorry)
D d;
std::unique_ptr<T,D&> p1( new T, d );
std::shared_ptr<T> p2( std::move( p1 ) );
typedef std::reference_wrapper<D> D2;
D2 * p3 = std::get_deleter<D2>( p2 );
assert( p3 != 0 );
assert( &p3->get() == &d );
