std::allocator and std::pmr::polymorphic_allocator should throw std::bad_array_new_length from their allocate member functions if the number of bytes required cannot be represented in std::size_t. libstdc++-v3/ChangeLog: * config/abi/pre/gnu.ver: Add new symbol. * include/bits/functexcept.h (__throw_bad_array_new_length): Declare new function. * include/ext/malloc_allocator.h (malloc_allocator::allocate): Throw bad_array_new_length for impossible sizes (LWG 3190). * include/ext/new_allocator.h (new_allocator::allocate): Likewise. * include/std/memory_resource (polymorphic_allocator::allocate) (polymorphic_allocator::allocate_object): Use new function, __throw_bad_array_new_length. * src/c++11/functexcept.cc (__throw_bad_array_new_length): Define. * testsuite/20_util/allocator/lwg3190.cc: New test.
