amosbird opened a new issue, #1761:
URL: https://github.com/apache/incubator-brpc/issues/1761

   It seems `SendRpcResponse` contains heap allocations 
(`butil::IOBuf::append`) which returns `-1` if malloc fails. This error code is 
silently dropped when building response. Do we have defined behavior when 
response is partially built and sent back to client?

   btw, can we mark `SendRpcResponse` as **noexcept** ?
