Using a delegating constructor to implement these constructors means that they instantiate the destructor, which requires the element_type to be complete. In C++11 and C++14 they were specified to be delegating, but that was changed as part of LWG 2801 so in C++17 they don't require a complete type (as was intended all along). PR libstdc++/87704 * include/bits/unique_ptr.h (unique_ptr::unique_ptr(nullptr_t)): Do not delegate to default constructor. (unique_ptr<T[], D>::unique_ptr(nullptr_t)): Likewise. * testsuite/20_util/unique_ptr/cons/incomplete.cc: New test. From-SVN: r265423 |
