Although the std::any constructors use decay_t to determine the type of the contained value, std::any_cast should use the un-decayed type (and so always fail for function and array types that decay to pointers). Using remove_cv_t is correct, because the condition for std::any_cast to return non-null is operand.type() == typeid(T) and typeid ignores top-level cv-qualifiers. PR libstdc++/90220 * include/std/any (__any_caster): Use remove_cv_t instead of decay_t. Avoid a runtime check for types that can never be stored in std::any. * testsuite/20_util/any/misc/any_cast.cc: Test std::any_cast with array types. From-SVN: r270547 |
