The value returned by Message::ByteSize() does not match the actually
number of bytes that are consumed after writing a message to a
stream. Example:
some_message m;
/* ... populate m ... */
size_t len = m.ByteSize();
int pos = boost::iostreams::position_to_offset(stream.tellp()); /*
save the current position of the stream */
m.SerializeToOstream(&stream);
/* and now this assert will fail */
assert(pos + len == boost::iostreams::position_to_offset
(stream.tellp());
Maybe I'm missing something here, but shouldn't the value returned by
ByteSize() be the same as the actual number of bytes written to the
stream?
