Description

I have the problem while using Header exchange.The queue and binding to header exhcange are created.The args of binding is very long,so have Seg fault.And then I find the bad point at Buffer::putRawData(const string &s)
The code as follows:
uint32_t len = s.length();
s.copy(data + position, len);
position +=len;

If the length of string s is greater than the length of data, then error occurrs. Why don't check the length and then copy?
