// The deeply nested payloads of the recursion-limit performance tests
// (binary_recursion_limit_test.cc).  They are built directly on the wire
// rather than serialized from a message object of that depth.  ByteSizeLong(),
// the serializer and the destructor recurse once per nesting level, which
// overflows the stack under the sanitizers' larger frames (b/563731788).  The
// bytes are identical to what the message objects serialize, which
// recursion_limit_payloads_test.cc checks at a depth the stack can take.
