We need to fix the type of allocator passed to a publisher and a subscriber, otherwise, extra memory space is allocated at various parts of
rcl.For instance, a memory area of size
sizeof(rcutils_string_map_impl_t) * sizeof(MessageT)is allocated here.This bug not only causes extra memory consumption, but also causes
std::bad_allocin the publisher (and subscriber) that handles the message type when a huge message (larger than a few hundred MB) such as static size array is defined.backport #1657
