The class template semiregular-box<T> of [range.semi.wrap] is specified to value-initialize the underlying object whenever its type is default initializable. Our primary template for __detail::__box respects this requirement, but the recently added partial specialization (for types that are already semiregular) does not. This patch fixes this issue, and additionally makes the corresponding in place constructor explicit (as in the primary template). libstdc++-v3/ChangeLog: * include/std/ranges (__detail::__box): For the partial specialization used by types that are already semiregular, make the default constructor value-initialize the underlying object instead of default-initializing it. Make its in place constructor explicit. * testsuite/std/ranges/adaptors/detail/semiregular_box.cc: Augment test. |
